Yes, you can cancel a British Airways (BA) flight, but the amount you get back depends heavily on your ticket type and when you cancel. Under BA’s 2026 policy, if you cancel within 24 hours of booking, you are usually entitled to a full refund to your original form of payment, provided the flight was booked at least 24 hours before departure. Beyond that initial window, if you have a "Flexible" or "Fully Refundable" ticket, you can cancel and receive your money back, though sometimes a small administrative fee applies. However, if you hold a "Basic" or "Standard" (non-flexible) economy ticket, you generally forfeit the fare unless you are canceling due to the death of an immediate family member or a documented medical emergency. In most cases for non-refundable tickets, you will only receive a refund of the government taxes and fees, which is often a fraction of the total price. If BA cancels the flight themselves, you are legally entitled to a full cash refund or a rebooking. Always check the "Manage My Booking" portal on the BA website for your specific "Cancellation Terms."
