Of all the myths surrounding travel and finding cheap flights, one stands out. We hear it again and again and again, from beginners to even so-called travel experts and social media influencers. You've probably heard it too – it's practically common knowledge.

“You should search incognito for flights or clear the cookies on your internet browser because the website is tracking what you're looking for and will jack up the price.”

Let us say this unequivocally: Searching for flights incognito does nothing. Absolutely nothing. Nor does clearing your cookies. And we are experts at airfare and finding cheap flights.

At Thrifty Traveler, we find flight deals for a living and send them to Thrifty Traveler Premium members. We're searching all day, every day for flights. If airlines were tracking our searches, we'd never find cheap flights. And trust me, we do.
 

 

Pssst… that thing you've heard about booking on Tuesdays is wrong, too. There's no best day to book flights, either.

It sounds like it makes sense, right? The idea that you're being tracked is an easy explanation for why the price of a flight you were looking at changed an hour later when you went to go book. Searching incognito for flights makes travelers feel like they've got the power – like they're beating the airlines.

But it's just not true. Airlines are not tracking your searches. Neither is Google Flights – the best search platform for finding good deals on airfare – or most other search engines and online travel agencies (OTAs) like Expedia and Priceline. Your flight searches aren't being affected by your previous searches.

So what's the answer behind the constantly changing flight prices, then? Why did that ticket you were looking at suddenly jump in price?

 

Explaining Changes in Airfare

The reality is that airfare pricing is fickle, and it's always changing. Airlines are constantly altering their prices as tickets sell and demand changes.

One simple explanation behind a sudden change in price is something called the airfare's fare class. While you just see economy and first class when you walk on the plane, airlines sell an alphabet soup's worth of tickets called fare classes – and it’s literally an alphabet, as most airlines have a fare class for every letter.

Here's a look at just some of United Airlines' fare classes, for example.
 

united fare classes 

There are close to a dozen or more different fare classes for even a standard economy seat, each with its own set of rules for upgrades, earning miles, and more. Basic economy fares – the bare-bones tickets sans seat assignments or checked baggage – are represented by an entirely different fare class. Even award fares booked with miles have a distinct classification.

Here's the important part: Every fare class has its own price. So when the cheapest fare class sells out – or an airline simply decides to remove that fare class – the price will jump up to the next, higher-priced class.

So let's say you're looking at roundtrip flights from Minneapolis-St. Paul (MSP) to Las Vegas (LAS) on Google Flights and you see a good deal for $157 roundtrip. Little do you know, there's only one ticket remaining at that price.
 

delta flights 

So when you go back an hour – or even just a few minutes – later and find that price is gone, it's not because Delta is tracking your searches. That cheapest ticket likely just sold. Or Delta decided to pull it.

That's it. These quirks with airfare classes and pricing explain 90% or more of the frustrating fluctuations you may see.

In some cases, you might be searching through Google Flights and click through to book a good deal only to find the price has shot up. But again, it's not that you're being tracked. Instead, because flight prices are changing constantly, sometimes Google Flights will erroneously display an out-of-date price that has since changed due to cached data.

Those mismatches typically get fixed within minutes, if not seconds. But every once in a while, it may look like Google Flights or your airline have tried to pull a fast one on you.

 

What About Using a VPN to Find Cheaper Flights?

Right after searching incognito and clearing your cookies, using a VPN (virtual private network) to disguise the location you're searching from might just be the most frequently repeated travel tip for finding cheap flights. In this case, it can sometimes work … but not for the reasons you may think.

It's not about how you're searching: It's about where you're searching from. Some flight search platforms and even individual airlines can charge drastically different amounts based upon the point-of-sale – or at least where

Whether you use a VPN or simply navigate through an airline's website to select a different location, it can result in some savings … or additional costs. For example, when I needed to book flights from Bogota (BOG) and Cartagena (CTG) and back earlier this year, searching from the U.S. yielded roundtrip fares for just over $111.

But after switching my location on Avianca's site to Colombia itself, it pulled up the exact same flights at 354,000 Colombian pesos – dropping the price by $30 apiece to $81 USD.

If you're trying this money-saving method, make sure you've got a credit card that doesn't charge foreign transaction fees!

But don't assume that searching from the home country (and paying in its currency) is always the key to savings. For example, these long-haul flights from New York City (JFK) down to Buenos Aires (EZE) on Aeromexico clock in just over $1,000.

By switching my point of sale to Argentina itself, the exact same flights cost 229,637 Argentine pesos. That works out to more than $1,719 USD – an extra $700!
 

new york city argentina 

Let me be clear: This is incredibly hit or miss. You could run 100 searches around the globe and only run into this issue once or twice. It just depends on where you're flying – and where you're buying.

Is it worth trying? Yes, especially if you don't like the prices you see on a flight abroad, change your point of sale or fire up a VPN and compare the prices.

But though this technique can help at times, it's by no means a silver bullet to saving on flights.

 

Bottom Line

If you really want to know how to find cheap flights, you need to know the facts.

You can search incognito for flights if you want, but it's not doing you any good. And stop wasting your time clearing your cookies, too. These tips have been passed around for years even by so-called experts. But it's simply not true.

  • Agree to disagree about Google Flights being totally comprehensive…I recently spent about a week tracking prices on an international route using Google, Kayak, and Expedia. Several of those days there were ideal flights (including the one I ended up booking) on the latter two that weren’t showing up on the former. It’s a very useful tool, but it shouldn’t be the only one. Also, I think ITA Matrix (owned by Google) is infinitely more useful and powerful than Google Flights–not sure why they keep them separate.

    • I mean it is comprehensive compared to other OTAs. Google Flights typically pulls from the airlines, Priceline, and Expedia, which should generally find the cheapest fare (9 times out of 10). Yes, ITA is more powerful, as it’s the backend for Google Flights, but it’s:
      A. Slow as hell.
      B. You can’t book with it.
      C. The average joe sure won’t be able to figure it out.

  • NOOOO! The Tuesday thing can’t be true. I typically find the best deals on Monday and Tuesday. I have NEVER searched the same flight after a Tuesday and found a lower price. It’s typically around $100 more for the same exact flight every other day I look. When using the app Hopper to monitor flights it also typically shows the lowest prices on Tuesday. Coincidence or conspiracy who really knows?

  • The issue for me is not that the fare increases, it is that I Don’t always see the lower price. If I change computers(up address) I find lower fare. And what about point of sale

    • This will not happen if you use Google Flights. If it does it is only due to the variability of fare pricing.

  • My husband and I were sat on the sofa on separate devices. I was showing him a low cost flight ai had found earlier. However on his phone all the flights shown were £5 cheaper than mine. That’s £20 difference on a low cost return flight.

      • “this generally should not happen” haha. Don’t you mean “that is impossible! ”

        You have no idea what you’re talking about buddy. Just another guy trying to chisel out a new career as a blogger.

  • Travelport tracks ALL flight searches. They sell that information to all of the flight search engines.
    They all pull from the one database of tracked flights.

  • “Here’s the important part: Every fare class has its own price. So when the cheapest fare class sells out – or an airline simply decides to remove that fare class – the price will jump up to the next, higher-priced class.”

    I can’t believe it is mere happenstance that the lowest fare classes so frequently list “one fare remaining at this price” or “two fares …” or some similarly tiny number, regardless of whether my search is a month before the flight or six months. My suspicion is they are falsely stating the number of fares remaining in an effort to instill a sense of urgency in me. Now, it MAY be that it is not “fare classes” in which so few tickets at the listed price remain, but rather some kind of smaller bucket. If an airline has 50 different fare buckets, then I suppose they could truthfully claim only “one fare remaining at this price” (in this tiny bucket, after which we will list fares in the next higher tiny bucket). Though it may satisfy the letter of the law, it still feels less than candid to me.

  • This is categorically untrue. I know that some airlines do it because I have experienced it with Cathay Pacific back in 2015. I had the exact same flight on normal browser and incognito window and the normal browser was double the cost.

    • Agree! It happened with me as well. The Author probably hasn’t experienced it yet and has put out a blanket statement saying its untrue *smh*

      • We search hundreds, if not thousands of fares, every single day. If airlines were tracking searches, it would have happened to us – and we’d probably never find flight deals.

  • Sorry this is a bulls..t claim. I observed this actually couple weeks ago myself. I found a fare on Google Flight, by accident I closed the page. I quickly reopened it and do the search again and voila, the same flight cost couple hundred more. I did search again on a different computer with a different IP and got the old price back.

    Airlines most likely use the same techniques advertisers are using. They likely pay more to aggregators if they can uniquely identify users, then they provide an individualized price for each user. As the same user is searching for the same flight price is artificially increased, to give impression that tickets are being sold out.

  • This is all complete nonsense. I know first hand that there are better and worse times to book flights. This guy has no credibility after reading that.. Take what you read on the internet with a grain of salt people.

  • I am a Thrifty Traveler premium member and I sadly have to disagree with a majority of this post. I too have experienced a price increase when I kept looking up the same flight several times within a day. There weren’t any notifications on the main class cabin I was looking at to say it was “only 1 seat left at this price” or such language either. After looking up that flight several times the price jumped 500 miles. I wasn’t sure if I wanted to take that flight so I kept waiting, checking on it several times within the same week. The more I looked it up, the price kept increasing. Finally I stopped looking at it for a week or so and boom, the price dropped back to the “normal” mileage cost for that flight. This has happened a few times to me, so I believe that the airlines ARE monitoring how popular a flight is in their searches and if it’s one that’s been searched a lot, they increase the price. They would easily have all that data from their website on which flights are poplar and which aren’t. I just don’t understand how every time it is mere coincidence.
