Before you travel

How do I check this flight for my travel date?

Use the airline’s or airport’s official flight lookup with your flight number and the departure airport’s local date. Compare the airports and operating airline with your ticket; a schedule verified for one date does not confirm every departure.

Where should I go for check-in or baggage help?

Open the airport and airline details for the relevant stop, then check your flight on the departure screens. Check-in, ticketing offices and arrival baggage desks serve different purposes; use the contact that matches your issue.

What evidence should I keep after a delay or cancellation?

Keep your ticket, boarding pass, airline notices and relevant receipts. Follow the operating airline’s certificate procedure and your insurer’s document requirements; a certificate request does not by itself establish entitlement to payment.
