Key takeaways

Flexibility is the biggest lever - dates, nearby airports, and sometimes destination move the price far more than any booking trick.
Book direct with the airline when you can - Reddit is near-unanimous that third-party resellers cause more pain than they save.
Judge every fare against a baseline - cheap only means something versus the route's normal price.
Let alerts watch for you - a wishlist app like Snagfly flags verified 50-90%-off drops on the routes you pin.

Flexibility beats every "trick"

The single most repeated point across r/travel, r/Flights and r/Shoestring: the cheapest booking comes from being flexible, not from a secret hack. Flexible dates (mid-week and shoulder season), flexible airports (price every airport in a metro), and, when you can, a flexible destination. Everything else is a rounding error next to this.

Book direct with the airline

Reddit's other near-consensus: once you find the fare, book it directly on the airline's site rather than through an online travel agency or a "cheap ticket" reseller. Direct booking makes cancellations, schedule changes, refunds and irregular-operations far easier to handle - the small savings a reseller sometimes shows rarely survive one disruption. This matters even more for a mistake fare, where booking direct and waiting before you plan around it is the safe play.

Myths to drop

Incognito doesn't lower fares. Repeatedly debunked - airlines don't reliably raise prices because you searched twice.
No magic "cheapest day to book." The old "book on Tuesday at 1am" rule doesn't hold; prices move by route and demand, not a weekly clock.
VPN "country hopping" occasionally surfaces a different currency price but usually breaks on payment or the fare rules - not a dependable strategy.

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.

Use a baseline, then pounce

A price is only "cheap" against what the route normally costs. Experienced Redditors eyeball a route's usual range before calling anything a deal - or hand that job to a tool. Snagfly measures every fare against the rolling 90-day median for that exact route and only flags a fare at least 50% below it, so you're comparing to real observed prices instead of a headline discount.

Let alerts do the watching

Nobody can refresh a route all day. Two layers cover it: set a free Google Flights price alert for a trip you've already planned, and pin your wishlist in Snagfly for the destinations you want but haven't dated. Snagfly watches those routes 24/7 and emails you - capped at three a week - only when a genuine 50-90%-off fare appears, then sends you to the airline to book.

The cheapest-booking workflow, in one line

Stay flexible, judge fares against a baseline, let alerts catch the drop, and book direct. A wishlist app rolls the baseline, the watching, and the book-direct handoff into one - for the destinations you actually care about.

FAQ

What's the cheapest way to book flights according to Reddit?

Reddit's consensus workflow: stay flexible on dates and airports, compare fares against the route's normal price, use free price alerts so you don't have to keep checking, and book directly with the airline. For destinations you already know you want, a wishlist alert app like Snagfly watches those exact routes and flags verified 50-90%-off drops for you.

Is it cheaper to book directly with the airline or a third-party site?

Reddit strongly favors booking direct. Third-party resellers occasionally show a slightly lower price, but changes, cancellations, refunds and disruptions are much harder to resolve through them - and that cost usually erases the small saving. Book direct, especially for a mistake fare.

Does incognito mode or a VPN get you cheaper flights?

Not reliably. Incognito is one of the most debunked myths on Reddit - airlines don't dependably raise fares because you searched before. VPN currency-hopping sometimes surfaces a different price but often breaks at payment or on fare rules. Flexibility and alerts save far more.

How do I get told when a route drops in price?

Set a Google Flights price alert for a route you've planned, and for destinations you know you want but haven't dated, pin them in Snagfly. It watches those exact routes 24/7 and emails you - capped at three a week - only when a fare drops at least 50% below the rolling 90-day median, then links you to the airline to book.
