12 Flight Cancellation Refund Rules Every Passenger Should Know (2025 Update)

9. Documentation and timing: what to keep

Rule summary: Good documentation speeds refunds. Save booking confirmations, payment receipts, screenshots of notifications, boarding passes, baggage tags, and any emails or texts from the airline. Note dates and times of conversations with airline staff and save names where possible. These items form the evidence you’ll need if the airline delays or denies a refund. Practical checklist: 1) booking confirmation with fare and charges, 2) proof of payment showing method and date, 3) screenshots of schedule changes or cancellations, 4) any in‑airport reports like a PIR, 5) receipts for essentials or alternate transport. Keep digital copies in a single folder or email thread for quick access. Timing note: submit your refund request right away after a cancellation or qualifying change. Early requests often get faster processing. If the airline confirms a refund, jot down the confirmation number and the expected processing date. If the expected timeline (seven business days for credit cards, up to 20 days for other methods) passes without a credit, escalate immediately.
