British Airways offers a flexible cancellation policy for its passengers. If you have a refundable ticket, you can cancel your flight and receive a full refund. Non-refundable tickets may also be eligible for a refund if you cancel within 24 hours of booking. In case of flight cancellations initiated by British Airways, you are entitled to a full refund or to be rebooked on an alternative flight. If your flight is delayed, you may be eligible for compensation depending on the length of the delay and the distance of your flight. To request a refund or to make changes to your booking, you can visit the British Airways website or contact their customer service team.
