You were planning to travel on British Airways, and you booked flight tickets. Suddenly, there is a change in your travel plan for any reason and you want to cancel the flight. The British Airways cancellation policy provides easy and smooth cancellation for passengers. You can cancel your flight ticket within 24 hours of booking and at least 7 days before the travel date to receive a full refund. There are some other details, such as if a flight is delayed more than 3 hours without adding travel insurance to the booking, then British Airlines will provide a full refund for your cancellation.
