Quick answer: Compare the original payment line by line with the refund breakdown. A partial refund may reflect used segments, non-refundable add-ons, fees, currency conversion or a calculation error.
Ask for a written breakdown
- Base fare
- Taxes and government charges
- Seat and baggage fees
- Agent service fees
- Used or reissued segments
Check currency and card effects
Exchange-rate movement and issuer fees can make the credited amount appear different. Ask for the original refund currency and amount.
