Yes, British Airways has a 24-hour cancellation policy that allows you to cancel your flight and receive a full refund if you do so within a day of booking, as long as your flight is scheduled for at least a week later. This is a great way to ensure your travel plans are flexible without incurring fees. For tickets that fall outside this timeframe, cancellation charges may apply based on the fare type. For assistance and more information, please visit the British Airways customer service page.
