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 results link to several different sites with your trip pre-filled, 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.
