Key takeaways
- Airfare and seat inventory change continuously; recheck the live fare before payment.
- Compare the final total, not just the first price shown.
- Confirm who sells/services the ticket and read baggage, change and cancellation rules.
A good flight comparison puts like-for-like itineraries next to each other and then checks the differences that can change the real value of a ticket.
Compare identical itineraries first
Start with the same flight numbers and fare type so price differences are meaningful. Then compare alternate schedules and airports separately.
Know who is selling the ticket
Airline sites, online travel agencies and metasearch engines play different roles. The company taking payment or issuing the ticket is usually the key contact for changes and refunds.
Normalize baggage and flexibility
Two fares that look similar can include very different baggage, seat, change and cancellation conditions. Add those differences before calling one fare cheaper.
Recheck before payment
Inventory can change between search and checkout. Confirm dates, airports, passenger names, ticket rules and final total on the last payment page.
A current flight-search checklist
