British Airways offers flexibility for travelers who need to make same-day changes to their flight. If you wish to change your flight on the same day as your original booking, here’s what you need to know:

• Eligibility: Same-day flight changes are subject to availability and apply to flights on the same route and date.
• Fees: Depending on your fare type, a change fee and any applicable fare difference may apply. Some flexible fare options may allow changes without additional charges.
• How to Change: You can make changes through the British Airways website, mobile app, or by contacting their customer service. If you're at the airport, visit a British Airways customer service desk for assistance.
• Exceptions: Changes may not be possible for some fare types or routes, especially if the desired flight is fully booked.
