Flight booking tips

Book 6–8 weeks ahead

Domestic flights are cheapest 6–8 weeks before departure. For international trips, book 2–3 months in advance to secure the best fares.

Be flexible with dates

Flying mid-week (Tue–Wed) is often significantly cheaper than weekends. Use flexible date search options to compare nearby dates.

Use incognito mode

Flight prices can increase when you repeatedly search the same route. Browse in incognito/private mode to see true prices.

Compare multiple sites

No single site always has the cheapest price. Our search opens results on 6 different engines so you can compare effortlessly.

Consider nearby airports

Flying into a nearby secondary airport can save you hundreds. Check alternate airport codes for your destination.

Set price alerts

Most flight comparison sites let you set price alerts. Google Flights is particularly good — it will email you when prices drop.

Check budget airlines separately

Budget carriers like Ryanair and EasyJet sometimes do not appear on comparison sites. Check their websites directly too.

Try one-way + one-way

Two one-way tickets on different airlines can be cheaper than a round-trip, especially on budget carriers.
