How to find cheap flights, according to Reddit
Travel subreddits have argued about cheap flights for years, and a surprisingly consistent playbook has emerged. Here's what Reddit actually agrees on in 2026 - the tactics that work, the myths worth dropping, and where to let alerts do the work.

Key takeaways
- Flexibility beats tricks. The single most-repeated Reddit tip is being flexible on dates, airports, and sometimes destination.
- Incognito is a myth. Clearing cookies doesn't meaningfully change fares - the community has debunked this for years.
- Use a baseline. A "cheap" fare only means something against the route's normal price.
- Let alerts watch for you. Set price alerts and, if you know your destinations, pin them in a wishlist app like Snagfly for verified, capped drops.
1. Flexibility is the whole game
If Reddit agrees on one thing, it's this: the cheapest fares reward flexibility. Flexible dates (mid-week, shoulder season), flexible airports (check every airport in a metro - JFK/LGA/EWR, or LAX/BUR/SNA), and sometimes a flexible destination. The less locked-in you are, the more room a deal has to find you.
2. The free tools Reddit actually uses
- Google Flights - the community default. Use the Explore map for "anywhere" ideas, the date grid to see the cheapest days, and price alerts on routes you like.
- Skyscanner - handy for "everywhere" searches and month-view browsing.
- Point.me and award charts - when the goal is miles rather than cash (r/awardtravel territory).
3. Drop the myths
Two things Reddit has debunked repeatedly:
- Incognito mode doesn't lower fares. Airlines don't meaningfully raise prices because you looked twice. Search normally.
- There's no magic "cheapest day to book." The old "book on Tuesday" rule doesn't hold up - prices move by route and demand, not by a weekly calendar. (More on that in our best time to book guide.)
4. Judge a deal against a baseline
A number is only "cheap" relative to what the route normally costs. Experienced Redditors eyeball a route's usual range before calling anything a deal. You can do this by hand - or let a tool do it. Snagfly measures every fare against the rolling 90-day median for that exact route and only flags a fare that's at least 50% below it, so you're comparing against real observed prices, not a headline discount.
Skip the endless fare-checking
Pin the destinations you actually want. Snagfly watches those exact routes 24/7 and emails you only when a fare drops 50-90% below its verified baseline - capped at three a week.
5. Let alerts do the watching
Nobody can refresh routes all day, and the whole thread history of r/Flights is people missing a deal because they weren't looking at the right moment. Two layers cover this:
- Set price alerts on specific routes in Google Flights for trips you've already planned.
- Pin your wishlist in Snagfly for the destinations you know you want but haven't dated yet. It watches those routes 24/7 and emails you - capped at three a week - only when a genuine 50-90%-off fare appears.
6. Book direct once you find it
A near-universal Reddit rule: after you spot the deal, book directly with the airline where you can. It makes changes, cancellations, and disruptions far easier to handle than going through a third-party reseller - and if it's a mistake fare, booking direct and waiting before making plans is the safest play. Snagfly is built around this: it finds the drop and sends you straight to the airline, taking no commission on your booking.
The Reddit stack, in one line
Stay flexible, browse with Google Flights, ignore the incognito myth, judge fares against a baseline, let alerts watch your routes, and book direct. A wishlist app like Snagfly rolls the baseline, the watching, and the book-direct step into one - for the destinations you actually care about.
