British Airways allows cancellations based on the type of ticket purchased. Refundable tickets can be canceled for a full refund, while non-refundable tickets may incur a fee or offer only a voucher for future travel. Cancellation requests made within 24 hours of booking are typically eligible for a full refund, regardless of ticket type. Changes or cancellations due to flight disruptions, like delays or cancellations initiated by the airline, may qualify for refunds or rebooking options. Check specific ticket conditions.
