Finding cheap flights is as much about avoiding costly errors as it is about clever tricks. Here are the nine mistakes that quietly inflate your airfare — and how to stop making them.
1. Waiting for prices to "drop" indefinitely
Fares rarely fall the week before departure. Once you spot a genuinely good price inside the prime booking window, take it.
2. Only checking one search engine
No single site has every fare. Compare at least two flight search engines before you book.
3. Ignoring nearby airports
Flying into or out of a secondary airport an hour away can save a lot. Always run a "nearby airports" search.
4. Booking with fixed dates
Rigid dates cost money. Use the flexible-date calendar to shift a day or two toward cheaper midweek departures.
5. Forgetting to search incognito is overrated — but clearing bias isn't
Private browsing won't magically lower prices, but comparing prices logged out and logged in (for member fares) is worth a look.
6. Overlooking budget-airline fees
A cheap base fare can balloon with bag and seat fees. Always compare the all-in total, as covered in our budget airline guide.
7. Skipping price alerts
Alerts do the watching for you. Set them the moment you start considering a trip.
8. Booking one round-trip when two one-ways are cheaper
Mixing airlines with two separate one-way tickets ("hacker fares") is often cheaper than a single round-trip.
9. Not being flexible on destination
If you just want to get away, "Explore" and "Everywhere" searches reveal where it's cheapest to fly right now — and that's where the real deals live.
