Save emails, screenshots, booking details, receipts and any reference numbers.

Airlines FAQ
What information should I include in an airline complaint?
Include your booking reference, flight number(s), travel date, airports, a clear timeline of events, what you were told,
and what you want the airline to do (refund, reimbursement of expenses, compensation, rebooking, or a written explanation).
Can I complain by email?
Yes. A formal complaint email can use the same structure as a letter. Attach relevant evidence (receipts, screenshots, photos)
and ask for a written response.
How long should an airline take to respond?
Response times vary by airline, but you should expect an acknowledgement and a substantive reply within a reasonable period.
If your complaint is not progressing, keep communications in writing and consider escalation routes where applicable.
What if I’m claiming back expenses?
Provide itemised receipts and briefly explain why each cost was necessary. Keep the request specific (what you want repaid and why).
What if my refund is delayed or refused?
State the original payment date, what you were promised, and set a clear deadline for payment. Ask the airline to confirm next steps in writing.
