Ask about replacement travel and refunds

Before buying a new ticket, ask the airline or original seller about alternatives and how to request a refund or change. Keep the cancellation notice. Do not assume the original booking is automatically refunded.

Check connections and bags already checked in

Ask how the new itinerary affects onward travel, whether you need to collect checked baggage and where to get help. Confirm the new flight number, local date and airport, particularly if the replacement uses a different airport.

Keep cancellation evidence and separate later claims

Retain the original and replacement itinerary, written replies and case numbers. A refund request, a compensation request and an insurance claim are separate procedures. Use the country and carrier guidance linked below for the applicable conditions.

Which airline should I contact first?

Check the actual operating airline on the ticket. A marketing flight code or the booking seller may differ from the company operating the flight; use the relevant carrier guidance below.

Is a delay certificate the same as proof of travel?

No. They establish different things. Ask the receiving organization which document it needs and check the airline’s issue conditions.

Does reporting to the airline also file my insurance claim?

No. Keep the airline’s case record and separately check your policy’s cover, evidence and claim procedure.
