How to Find Cheap Flights – The Ultimate Guide

The Internet has made the world feel very small. With a Google or YouTube search we can look at pictures of or watch travel documentaries for any destination we could imagine, from Paris to Palau.

Using Google Earth, we can zoom in on a bird’s-eye view of the Pyramids at Giza, or with Street Views place ourselves on the cobblestones of Antigua or the peak of Mt. Everest. Through digital communication and content-sharing we make friends, clients, colleagues, and fans all over the world.

So why does the value of a dollar put the world so frustratingly out of reach?

As small as the world may feel, as easy as we can learn about these fantastic destinations, the fact remains that actually getting there on a jet plane is expensive.

Consumer airfare responds to market forces like:

  • The price of fuel oil
  • The expense it takes to produce, purchase, and maintain a jet airliner.

The result: airline tickets routinely cost hundreds of dollars over short distances; thousands of dollars for international flights. With the purchasing power of most American households in decline, these are hundreds or thousands of dollars many Americans can’t afford to spend on a luxury like travel.

To make matters more frustrating, the price on the same itinerary seems to change depending on where you look, as well as when you look. Sometimes one-way tickets are more expensive than the round-trip fares … direct flights may be more expensive than connecting flights … it doesn’t seem to make any sense. And every time you check, the prices seem to jump up a little. How can you possibly know if you are getting the best deal?

Meanwhile, those travel guides and travel channel shows taunt you, along with cultural noise from Instagram influencers telling you that you simply must travel in order to achieve fulfillment as a human being.

Maybe it’s more than just noise. Maybe you have friends and family you wish you could see more often. Maybe there’s a job opportunity that could change your life … if you could just show up for an interview on the other side of the country.

Long story short, the high cost of an airplane ticket stands in the way of many Americans living out their best lives.

This guide will arm you with strategies on how to find cheap flights. Airfare always costs money, but by making a few changes to your shopping habits, you can pay a lot less. At the very least, you can book with the confidence that you are getting the best possible deal.

You can even access bargain-basement rates on flights from the US to Europe, Asia, and other far-away destinations. Saving money on airplane tickets will allow you to:

  • See the world.
  • Access new opportunities elsewhere in the world.
  • Reconnect with faraway friends and family.


Finding cheap flights starts with a shift in mindset. Travel is expensive, but many hobbies are expensive. Sports, musicianship, dancing, motorcycle maintenance, pet ownership … from the equipment and tools, to the membership fees and licenses, to the lessons and training, all of them cost money.

If you want travel to be part of your lifestyle, start by making a conscious decision to make it a priority. Some of the money you may have expected to spend on other things will divert to your travel budget, starting now.

If your job makes it impossible to travel, it may be time to look for a new job. Maybe your boss will let you “work from home” for a few days while you travel … and you have to be willing to work while travelling and discipline yourself to get it done. Otherwise, your boss won’t ever allow you to work from home again.

If your bills eat up your entire paycheck, maybe you could find a way to eliminate some bills. Sublease your apartment while you are gone. Cancel insurance and data bills you won’t need while you travel. Sell your car and get a new one when you return.

If all of this sounds impossible, your mindset may not be where it needs to be to pursue the travel lifestyle, no matter how cheap the airfare. Take some time to consider what you really value in your life. When we want something, it helps to consider what we are willing to give up in order to get it.

Write down your travel goals in a journal or on a whiteboard. Start a “vision board” with pictures of dream destinations to inspire you. Affirm to yourself every morning that it’s only a matter of time before you hit the road.

Remember, you can always make more money, but you can never make more time. How we spend our limited time on Earth is one of the most consequential decisions any of us can make. If travel is important to you, now is the time to make it happen … or at least lay the groundwork. There will never be a better time.

Where there’s a will, there’s a way. It may not happen tomorrow, but with a commitment to the nomadic lifestyle, even people with modest budgets can make epic journeys happen.

Cheap Flights Rule #1: Be Flexible

Being flexible is one of the most important principles to saving on airfare. This includes being flexible about…

When you Travel

In most of the developed world, the “peak” travel months are mid-May to mid-September. If you fly during these months, you will never find the cheapest possible airfare.

Of course, this is when most people take their vacations, partially due to school schedules and partially due to the weather in the northern hemisphere. The increased demand is why flight prices go up during this season.

That said, plenty of destinations have beautiful beach weather in February … like the entire southern hemisphere and the Tropics. If you can plan your trip between mid-September and mid-May, you have an excellent chance of scoring an unusually cheap flight.

In addition to the month, try to be flexible about the week or even the day you travel, as well as flexible about your trip duration and return date. It will be much easier to target the cheapest flight itinerary possible.

Consider the alternative … if you absolutely have to time the trip to your June wedding anniversary, and you have to leave on Saturday and return seven days later, you’re going to have to take what you can get in terms of airfare.

Skyscanner’s month display shows the cheapest days to fly out. Being flexible on the days you fly will save a huge chunk of money. Look for this feature on other flight search options as well.

Where you Travel

Maybe you always dreamed of visiting Paris or Rome. There’s nothing wrong with that.

But what if a dynamite airfare popped up for a less-expensive European city like Lisbon? Dubrovnik? Krakow? Tallinn? Could you get excited about one of those cities? All of them are beautiful and steeped in history.

Consider not just the destination city, but the departure/return city. If you don’t live in a town with a major airline hub, consider positioning yourself to one for cheaper airfare.

For example, the Texas capital city Austin is a thriving, artistic, tech-forward city, but it is not the hub of international commerce that Houston is. Houston’s two airports (IAH and HOU) cover much more territory than AUS. If you live in Austin, are you willing to drive to Houston? Or better yet, could you take a long-distance bus? Megabus offers fares between Austin and Houston for as little as $2.50 if you book early enough!

When to Book

We can’t talk about cheap flights without addressing two unkillable questions:

  1. Can I get a cheaper flight by booking early?
  2. Can I get a cheaper flight by booking last-minute?

Booking Early

Booking early has certain advantages. Fewer seats may have been claimed, allowing you to pick a window, aisle, bulkhead, exit-row, or forward cabin seat if you prefer. Note that many airlines have instituted extra fees for desirable seats, like bulkhead or exit-row seats with more legroom.

Booking early can also help you achieve flexibility in your scheduling. If you need to request remote work days or days off to accommodate your trip, employers usually prefer that you inform them sooner rather than later. By giving your boss several months’ notice, you can pick the dates with the cheapest airfare.

There is no hard evidence to support the claim that booking months in advance yields substantially cheaper flights. Prices do increase three weeks prior to departure. Outside of that window, however, you could catch a great deal within a month of departure, or you could catch a bad deal six months before departure.

Airlines use “dynamic pricing.” To make a long story short, a computer algorithm sets the price of most flights when someone searches for a flight. This applies to online searches as well as phone bookings. In other words, where you look and when you book makes the difference in scoring cheap flights, not how far in advance you book.

Booking Last-Minute

Travel legend abounds with stories of people who scored fire sale prices on flights by waiting until the day of the flight. The logic holds that airplane seats become worthless when they go empty, so airlines drastically discount their leftover seats in hopes of monetizing them somehow.

In practice, this isn’t something you can count on. The airline doesn’t care about losing a few hundred dollars on an unsold plane seat. On the other hand, they could lose a fortune if they devalued their product by cutting prices at the eleventh hour. Once word got out, everyone would do it.

Much more common is for airlines to jack airfare up at the last minute, betting that someone who needs a flight on such short notice is a motivated (i.e. desperate) customer who will accept whatever price the airline sets.

If you walk up to an airline booking counter and ask to purchase a ticket for a flight departing today, expect a markup of 600% or more. If even one guy has to eat that cost, he covers the cost of six seats and keeps the value of their product high.

Booking last-minute is a poor strategy to score cheap flights unless we’re talking about standby tickets, which have their own pitfalls. More on those to come.

Shopping for Flights Online

The e-commerce revolution revolutionized airfare booking. No longer dependent on travel agents or phone agents, consumers could search for and book their own flights directly from the airline.

Of course, with so many airlines to choose from, consumers ended up relying on “travel agent websites” like Travelocity and Expedia, which operate like a search engine. Once you enter the flight parameters you are looking for, the search engine aggregates airfares from many carriers to show you the best matches for your desired itinerary, alongside the price. These websites, web apps, or mobile apps are called flight search engines or flight search engine apps.

The flight search engine marketplace has become crowded. Before you wade in, consider mastering a few tricks …

Use an Incognito Browser

So many consumers miss this step, and they end up overpaying for airfare as a result.

You may have noticed the ability to open an “incognito window” or “private window” in a web browser like Google Chrome or Mozilla Firefox. You might have thought that this is a safer and more private way to browse, but it isn’t really. Your IP address is still visible, your computer is still vulnerable to add-ons and attacks.

What a private browser does do is browse the web without caching website data or adding cookies. Basically, the browser forgets what it just browsed as soon as you leave the website.

Whatever flight search engine site or app you use, always browse from a private or incognito window—on both desktop and mobile devices!

If you search for an itinerary repeatedly on a non-private browser window, your browser cache will long the search. The search result will add cookies to the browser. If you search the same itinerary, even on a different flight search engine, the search engine or tracking app will notice those previous searches and results in your browser cache.

What effect does this creepy phenomenon create? Airfare quotes that creep up and up. The more you search that itinerary, the more expensive it becomes across all booking sites.

Flight trackers return the best price results the first time you search for themAn incognito browser window tricks the flight search engine into thinking that every search is your first search.

For Google Chrome or Safari, open an incognito tab by hitting Control, Shift, “N”. For Mozilla Firefox or Internet Explorer, hit Control, Shift, “P”.

Where to Look for Flights

So which flight search engine is best? That depends, in large part, on what you are looking for and how you like to search. If “cheap” is the goal, you definitely want to pick one that doesn’t inflate its fares (a la Expedia, Travelocity) or charge an extra booking fee (a la Bookit, OneTravel).

Here are some of the most popular flight search engines for how to find cheap flights.


Skyscanner is a “metasearch” engine, currently gaining popularity for its ability to cast a wide net. It actually scours other flight search engines for the best fares and then provides links to the actual booking page for the deal on another site. Cool features include:

  • An “everywhere” search feature, in case you aren’t married to a destination and want to discover an unexpected deal on flights to an unexpected place.
  • A “greener flights” feature to identify itineraries with below-average CO2 emissions.
  • Has a cheapest month and day display

Note that Skyscanner’s metasearch data may take you to outside flight search engines you have never heard of, with questionable reputations. So although Skyscanner finds some of the best deals, don’t count on getting a deal until you make it to the “Sale Complete” screen and get your booking confirmation number.

Google Flights

Tech giant Google surprised no one by dominating the flight search engine market upon its entry. Indeed, Google Flights has many features to recommend it, including:

  • A calendar display of fares so you can see which days feature the cheapest fares.
  • A “Price Graph” that adds an easy visual reference on which flights are the cheapest.
  • An at-a-glance map that shows the best fares for alternate routes within the region, in case you want to consider an alternate destination or return city.
  • Fare alerts (see below).
  • A streamlined, user-friendly interface with no ads or distractions.

ITA Matrix

Google Flights actually bought ITA Matrix and built its flight search engine on ITA Matrix data. ITA Matrix still exists as an independent website. It’s not the most user-friendly web tool, but once you master it you can easily search for better deals on alternative routes within a region—for example, the best fare between Texas and Europe, rather than the best fare between Dallas and Paris. ITA Matrix also breaks down the taxes and fees included in a booking fee so you know what you are actually paying for.


Kayak is the granddaddy of metasearch flight-finding tools. Google Flights stole some of its best tricks from Kayak, including a built-in fare alert. Since it features ads, Kayak has a busier, more distracting interface. However, its metasearch functions, along with the ability to search regionally or “anywhere” make it a force to be reckoned with.

The star of the Kayak show are the “Hacker Fares,” a feature Kayak uses to piece together itineraries from multiple websites. They take a little more effort to book, but you can access dirt-cheap itineraries if you thread the Hacker Fare needle.


If you don’t know where you want to go and can be flexible on your travel dates, TravelZoo may be the way to go. With the ability to search anywhere in the world by month or by season, you can discover inexpensive multi city itineraries that other metasearch flight search engines might miss.


Momondo stands out because, unlike competitors, it returns itineraries from Southwest Airlines (more on that later). However, it doesn’t tell you the price of the itinerary, only that the itinerary exists. You will have to go to to find the details and book the flight … but at least you know what to look for.


The Nomad tool from has one of the best UI for finding multi city and around-the-world itineraries.

It is best to look at a few search engines, as no one search engine returns the cheapest flights consistently.

GAME CHANGER: Setting Fare Alerts

One of the most powerful tools in booking cheap flights is to set a “Fare Alert” or “Price Alert” on a flight search engine that allows you to do so.

Pioneered by Kayak and adopted by Google Flights, a Fare Alert allows you to program an itinerary and receive email notifications when an unusually low fare surfaces for that flight.

You can even catch “mistake fares” this way. (More on that later.)

In Google Flights, setting up a flight tracker is as simple as logging into your Gmail or other Google account, doing a flight search, and clicking the toggle button marked “Track Prices.”

Once “Track Prices” is switched on, hit the “Search” button to execute the search. That’s it. When a low price on that itinerary pops up, a notification from Google Flights will land right in your email inbox.

If you want to track the price of a specific flight—say, the one direct service between your home city and a dream destination—Google Flights allows you to set a price alert on that flight in the search results page.

A Word About Southwest

No US airline is quite like Southwest. A unique blend of legacy and low-cost carrier, Southwest puts a lot of effort into marketing, branding, and customer service. Part of its distinct identity is that Southwest fares show up on no other flight search engines.

Southwest mostly serves the US domestic flight market, but does operate to Mexico and the Caribbean, as well as Hawaii and Alaska. If you seek any of these itineraries, make a point to check independently. They might have a great deal, but you would never hear about it from other flight search engines.

Other Places to Look


Many blogs offer valuable content to the budget-travel market. Examples include:

Check these blogs daily if you have time. Sign up for their email lists and follow them on Facebook, Twitter, or Instagram for up-to-the-minute notifications of cheap flight deals as they happen.

Airline Websites

Your email inbox is probably crowded enough, but airlines do maintain email lists. They use these lists to notify subscribers of airfare sales and promotional fares. Sign up for those email lists, and/or follow the airlines on social media to get notifications of great deals from the airline itself.

Facebook Groups

Travel hobbyists also set up Facebook groups to compare intel about cheap airfare. Search “Cheap Flights” or “Budget Travel” on Facebook, limit search results to “Groups,” and request to join.

You can even join Facebook groups specific to your city so you can find out about travel deals specific to your home time. As an added bonus, Facebook groups allow you to connect socially and make friends with people who share your passion for budget travel. You can swap tips and tricks!

Twitter and Instagram

Look for influencers in budget travel, including the above mentioned bloggers, and follow them on Twitter and Instagram. When they discover a deal and Tweet about it, you will get an instant notification.


You may have never thought of this, but it can reveal cheap flights that search engines won’t. When considering an itinerary, check out the Wikipedia page of the departure and destination airports. The airports themselves. For example, if you live in Boston, check out the Logan (BOS) airport website. If you dream of visiting London, check out the wikipedia pages for both Heathrow (LHR) and Gatwick (LGW).

The Wikipedia pages for these airports list the airlines that service them. You may discover an airline you never heard of that services both the destination and the return city, uncovering an inexpensive direct route you didn’t even know existed. You can then check for flights and fares directly on that carrier’s website.

Budget Airlines

The big names in commercial aviation—American, Delta, United—are sometimes referred to as “legacy carriers.” Other countries and regions have their own legacy carriers—All-Nippon Airways (ANA) and Japan Airlines (JAL) in Japan, for example, or Qantas in Australia, or Lufthansa and Air France in Europe.

These airlines are trusted names and members of alliances like the Star Alliance, oneWorld, or SkyTeam. They offer extra perks, premium cabins, and superior customer service. Because of all this, legacy carriers usually charge the highest fares.

Let’s leave legacy carriers behind for a moment. You can often score cheap flights from a low-cost or budget carrier. For example, you might have heard of:

With some of these carriers, many of them new to the aviation scene, you can find intercontinental airfare for under $500. That’s a great deal for an itinerary between, say, the US and Europe.

Within a country or region you might discover other low-cost carriers—for example:

Many of these airlines populate in the search tools, but With low-cost carriers in Europe, Asia, and the like, you can find regional flights for under $100 or even under $20 in some cases. You will never forget the day you booked Barcelona to Berlin on Ryanair for $17!

So what’s the catch? Three things to be aware of …

Some Flight Search Engines Don’t See Low-Cost Carriers

If you want to consider a low-cost carrier, make sure to use a flight search engine tool that can find them, or check the carrier website.

The Seats are Ultra-Economy

Don’t expect amenities like headphones, legroom, a seat that reclines deeply, or even inflight entertainment. The more prepared you can be to suffer some discomfort to get from point A to point B, the better.

They Charge for Everything

What really sets low-cost carriers apart from legacy carriers is that nothing is included except for the seat, the seatbelt, the safety equipment, and the lavatory.

You can expect to pay for things you may be used to receiving complimentary from other airlines, including but not limited to:

  • Seat selection.
  • Checked bags.
  • Carry-on bags.
  • Drinks, including water.
  • Snacks, including peanuts.
  • In-flight entertainment.

Once you start adding up the extras, the far looks much less appealing.

If your airfare goes from $300 to $450 due to add-ons, that still may feel like a pretty good deal for round-trip airfare from Boston to Berlin on Norwegian.

However, adding another $80 in fees on your Ryanair ride from Barcelona to Berlin may make that $17 base fare look like a tease.

With that in mind, here are some tips to get the most value out of your flight with a low-cost carrier …

  • Set expectations low. Don’t expect world-class customer service. Just be glad you’re getting a cheap flight. The lower your expectations are, the less likely you are to be disappointed by not having them met.
  • Pack light. The more luggage you bring on a low-cost carrier, the more you can expect the airfare to balloon with fees. This is a good tip for budget travel in general. More and more legacy carriers now charge for checked bags.
  • Don’t check a bag! In addition to the extra charges, some low-cost carriers have a bad record of losing checked luggage. Add to that subpar customer service, and you have a recipe for disaster if your bag doesn’t make it to your destination. Baggage claim also burns precious time in your destination upon arrival.
  • Bring your own snacks, drinks, and entertainment. This includes water or soda bought from the airport concessions stores, as well as music and video content pre-loaded and downloaded onto your mobile device. Don’t forget compatible headphones!

Credit Card Hacks for Cheaper Flights

Using credit card hacks to score cheap flights deserves its own ultimate guide, but the gist boils down to this: credit cards have the potential to reward you for your spending in ways that paying with cash or a debit card does not.

Some credit cards offer cash back; others offer travel rewards, which can be even more valuable than the cash back.

You can redeem these travel rewards to fly for pennies on the dollar, or even for free.

Imagine booking Paris to Los Angeles in First Class for $50 out-of-pocket. Do I have your attention?

Frequent Flier Miles—The Basics

“Frequent flier miles” are the loyalty points currency offered by airlines. They were initially called “miles” because how far you flew (on a cash ticket) determined how many “miles” you earned. Most airlines have done away with this system, and award “miles” based on how much cash you actually pay for a ticket.

You can earn a lot of frequent flier miles by spending tons of money on airfare. However, since this guide is about how to spend less on flights, let’s ignore that and focus on how travel-rewards credit cards can drastically reduce how much you pay for flights.

So how much is a “mile” worth? Airlines want them to be worth a penny apiece … but in practice they can be worth more.

The Annual Fee

Many travel rewards credit cards have an annual fee, usually in the $95 range. However, that annual fee can be drastically offset by perks such as …

The Sign-Up Bonus

Most premium issuers offer new cardholders a big supply of bonus miles or points if you meet a minimum spending requirement, usually $3,000 in the first 90 days but sometimes more, sometimes less. The sign-up bonus alone can often be worth upwards of $800 or more in airfare.

Accelerated Points Earning

Many airline cards offer one frequent flier mile per dollar on everything. You can do better than that. You should earn at least 1.5 frequent flier miles or two cents cash back per dollar spent, especially if you have an annual fee to offset. Some cards have bonus categories where you can earn two, three, four, or even five miles per dollar. Depending on the card, the bonus categories include dining, groceries, and gas.


Some travel rewards cards offer perks like priority boarding, lounge access, free checked bags, free travel insurance, and free primary car rental collision insurance.

Companion Tickets

A few airline credit cards (notably the American Airlines AAdvantage Aviator Red Mastercard and the Alaska Airlines Visa Signature card) offer an annual companion ticket, which you can use to fly with a friend or family member for drastically reduced fees, almost like a buy-one-get-one-free.

Two Transferable Points Cards to Look At

People don’t realize that the branded points offered by four different credit card banks are transferable. That means they can be changed one-to-one into frequent flier miles from a number of different airlines. Their cards tend to have accelerated earning plans, too.

Here are two credit card combos to consider:

Chase Ultimate Rewards

Chase Ultimate Rewards can be redeemed for 1.25 cents through the Chase travel portal, but can also be transferred one-to-one to many programs, useful frequent flier miles from United, Southwest, British Airways, and Singapore Air.

The card combo to get:

  • Chase Sapphire Preferred. $95 annual fee, big sign-up bonus, 2x points on dining and travel, primary car rental collision insurance, good travel protection package.
  • Chase Freedom Unlimited. No annual fee, 3x points per dollar on everything in the first year, 1.5x points per dollar on everything every year after that.

Citi ThankYou Points

Citi ThanYou points can be redeemed for 1.25 cents through the Citi travel portal, but they can also be transferred one-to-one to many programs, including useful frequent flier miles from Virgin Atlantic, Avianca, and British Airways.

These miles are even useful to US fliers because of airline alliances—these miles can be redeemed for flights on Delta, United, and American respectively.

The card combo to get:

  • Citi Premier. $95 annual fee, big sign-up bonus, 3x points on travel, entertainment, and gas, 2x points on dining.
  • Citi Double Cash. No annual fee, 2x points on everything.

NOTE: These are US credit cards. Different travel rewards credit cards will be available in different markets.

Travel Rewards Credit Card Don’ts

  • Don’t Carry a High-Interest Balance. 15% APR interest or more on a carried balance will erase the savings of your travel rewards quickly.
  • Don’t Start Overspending. According to NerdWallet, people tend to spend 12-15% more when it’s on credit cards vs. debit cards or cash. This will also erase the windfall of your travel rewards.
  • Don’t Miss the Sign-Up Bonus. Mark your calendar with the sign-up bonus deadline and make sure to make that spending limit! If you don’t usually spend $1,000 on credit cards in a month, you can divert the spending by pre-purchasing gift cards for gas or groceries, or using a charge-to-check mailing service like to pay bills.
  • Don’t Let Miles Expire. Some miles require account activity every two years, or the miles will expire. Stir up some account activity by redeeming a few miles, transfering a few points to miles, or spending a little on the credit card.
  • Don’t Use Travel Rewards for Non-Travel Purposes. You may see promotions that will allow you to use your miles and points for non-travel purchases. Don’t buy it! These non-travel uses typically get you less bang for your points.

Standby Tickets

Last-minute standby tickets used to be a great way to save money on airfare, provided that you could be flexible about when you flew. These same-day tickets entitled you to be seated on the next departing flight that had vacancies … provided that you weren’t bumped by a full-fare passenger or another standby with higher elite status in the airline’s loyalty program!

Today, standby tickets are not available for over-the-counter purchase from any US carrier. Some airlines allow certain tickets you already purchased to convert to a standby ticket if the passenger wants to change his or her itinerary to a different flight. An extra fee is usually charged for this privilege.

Since we’re talking about extra fees on an already-purchased ticket, standby tickets don’t have much relevance to the cheap-flight conversation anymore. It’s cheaper to be flexible and keep your booked itinerary, rather than change it at the last minute.

The exception is if you have a friend or family who works for the airline. That airline employee may be able to get you a free or deeply-discounted standby ticket as a job perk. If you score one of these tickets, remember to be flexible. Days could go by before a seat comes available for which you can use your standby ticket.

Additionally, your seat isn’t a lock until the plane leaves the departure gate. If a higher-status standby passenger shows up, you could be ordered to give up your seat, even if you have a boarding pass.

Erroneous Fares

Occasionally, airlines publish an erroneous fare. This could be human error, a currency conversion error, or a technical glitch. Regardless, the error could be discovered and fixed at any time, or an online booking may not complete. However, if you get to the “Purchase Complete” screen, the airline usually has to honor this erroneous fare.

Finding a fare error could be like finding a needle in a haystack—don’t stake your entire trip on it. If an accidentally low fare gets reported on a blog or social media group, it’s usually just a matter of time before the airline fixes the error. There are much more predictable ways to minimize your airfare expense.

Prowling for erroneous fares isn’t a sound strategy for budget travel, since it can never be counted on, unless it is caught by fare alerts you have set or revealed by content creators or social media groups you subscribe to. Still, if you discover an erroneous fare and manage to complete the purchase, by all means revel in your victory over the system!
