I wanted to know how people actually find cheap flights, not from another listicle written by someone who's never chased a fare down in their life, but from real travelers talking to each other, in their own words.
So I went to a community that's been obsessing over exactly this question since 1998: FlyerTalk, the forum frequent flyers have used for decades to trade tips, gripe about airlines, and occasionally build their own tools when nothing else does the job.
I spent the better part of a week reading through dozens of threads across FlyerTalk's Travel Tools, Budget Travel, TravelBuzz, and Online Travel Booking forums. Here's what actually shows up, over and over, when real travelers ask each other how to fly cheap.
Strip away the branding and almost every thread lands on the same starting point: Google Flights and ITA Matrix (the power-user tool Google acquired years ago and still runs at matrix.itasoftware.com).
When one traveler asked for the best way to find cheap, flexible-date tickets to Zurich, the replies were almost a chorus. User moondog's entire answer was just "Google flights." User pinniped added the context: "Google bought ITA... Google Flights is probably the best place to start."
User GREAKLY laid out the full workflow in a separate thread:
First check matrix.itasoftware.com to have a complete picture. Then play with kayak.com to find the site with the best fare and schedule. Once you found that site, buy the ticket from it via any cashback site.
Three tools, three separate steps, done by hand. That workflow, repeated in thread after thread, is basically a manual version of what a good flight search tool should be doing for you automatically.
If there's one idea that shows up more than any other, it's this: the biggest lever isn't a secret website, it's flexibility. On dates, on airports, sometimes on the destination itself.
In that same Zurich thread, user Yoshi212 didn't just suggest flexible dates, they suggested flexible airports too, checking fares out of Portland, Vancouver, Bellingham, and San Francisco in addition to the traveler's home airport of Seattle. User ChangingNappies took it a step further, recommending rome2rio.com to map out alternate airport options and ground transit costs, then running each candidate route back through Google Flights or ITA to compare.
In a thread about cheap international flights out of LAX, user Romelle gave nearly identical advice: "Try www.google.com/flights. Put LAX in your origin... and then something general like SOUTH AMERICA," and check nearby airports for a better fare.
This is exactly the principle I built FlightList around. Instead of picking one date and hoping, you search a whole window of dates and let the cheapest one surface itself. Reading these threads, that's not some clever trick I invented, it's just what serious frequent flyers have been doing manually, one search at a time, for years.
Not everyone wants to do the legwork themselves, and a decent chunk of FlyerTalk has fully outsourced the job to fare-alert subscriptions, Scott's Cheap Flights above all.
In a thread about last-minute deals, user Youngtraveldude was blunt about it: "Been subscribed for over a year... and WELL worth it. Daily you get emails with amazing deals." User Daedalus7 recommended the same service in the LAX thread, and user rjw242 pointed to Google Flights' own map view as a free alternative: "Google Flights has a nice feature where you can enter the dates and see a map of destinations and prices."
User Cloudship described almost the same technique in more detail: "enter in the departing airport, then leave the destination blank and look on the map. Be sure to zoom in and out, though, as the cheapest flights don't always appear first."
Whether people pay for the alerts or build the habit of checking the map themselves, the underlying behavior is identical: someone (or something) needs to be watching prices continuously, because the traveler isn't going to refresh a tab fifty times a day.
Some advice shows up so often it's practically folklore at this point. Browse in an incognito window so cookies don't drive prices up on repeat visits. Keep an eye out for error fares. Book directly with the airline once you've found your price.
A user named Chris1984 laid out a whole list of these, including a nice bit of honesty about error fares: "Finding one of those error flight fares can save you a ton of money, but you kind of need to be lucky." On flexibility specifically, they put it even more starkly: "If you are able to be flexible by lets say, quitting your job, you have full freedom on where to go."
That thread has a funny footnote, too. A moderator closed it for review before anyone else could weigh in, which is a very forum thing to happen and a good reminder that not every "study" of a discussion board gets the full discussion.
A separate cluster of advice is about actually finding budget carriers in the first place, since Ryanair, Wizz Air, and similar airlines often don't show up on the big aggregators. In a thread from a first-time European traveler, user Oditszapc pointed to Kiwi.com specifically for this reason, while user zarakazuki listed off Travelfika, Skyscanner, Momondo, and Hopper, and user john_ny described Skyscanner and Kayak in almost textbook terms: "This is a flight search engine that compares prices from hundreds of airlines."
But the same thread had a word of caution from user WineCountryUA that's worth repeating: "cheap tickets come with consequences — such as non-changeable, may no mileage earning, many hidden fees." Cheap on the aggregator doesn't always mean cheap once you add a bag and a seat assignment. More than a few replies across these threads amount to the same warning: know what you're giving up before you click buy.
No study of "how to fly cheap" discussions would be honest without mentioning hidden-city ticketing, better known these days as skiplagging: booking a flight with a layover in your real destination and just not taking the final leg.
FlyerTalk has been arguing about this since long before the term "skiplagging" existed, in a master thread that's been running for years. The consensus, echoed in a separate FlyerTalk piece on why the site's own writers avoid it, is that the risk isn't worth it for most people: you can only carry on, you can only book one-way, and if you're caught, airlines have gone as far as billing skiplaggers directly or shutting down their loyalty accounts. It's the rare piece of "cheap flight" advice that the community mostly tells people not to use.
My favorite thing I found wasn't a tip, it was a pattern. In more than one thread, someone showed up not with a recommendation, but with a tool they'd built themselves because nothing else did quite what they needed.
In the same thread as GREAKLY's workflow above, user abimatov mentioned a site they'd helped build, TravelWits, describing what it does in a way that sounded very familiar to me: it "finds remote airports at origin/destination, and what it costs to get there." Elsewhere on FlyerTalk's Travel Tools forum, other travelers have quietly launched their own award-search and flexible-search projects, PointsYeah and AwardTool among them, built by frequent flyers scratching their own itch after getting tired of stitching together Google Flights, ITA, and Kayak by hand.
I noticed FlightList never came up by name in anything I read, which is fair. It's a smaller, newer tool than Skyscanner or Scott's Cheap Flights, and I'm not going to pretend a search turned up mentions that weren't there. But reading through all of this, the gap it fills is exactly the one people keep describing: the manual, multi-tab, check-nearby-airports-and-flexible-dates routine that shows up in nearly every single thread. That routine is precisely what I got tired of doing by hand, which is the whole reason FlightList exists.
None of what I found on FlyerTalk is a secret. It's mostly just work: check more than one date, check more than one airport, watch the price for a while, browse without your cookies stacking the deck against you. The travelers who consistently land the best fares aren't the ones with an inside connection, they're the ones willing to do that legwork, or willing to hand it off to a tool that does it for them.
