Switching dates or times on a British Airways ticket works best through the Manage My Booking tool on the airline site. Most people manage it themselves in a few minutes if the fare allows it.

Start by grabbing your booking reference. It is the short code on the confirmation email or e-ticket, often called the PNR. Enter that plus the passenger last name into Manage My Booking. The page loads your full itinerary right away.

From there look for the change flight option. Select the sector you want to adjust, then search for new dates or times. The system shows what is available and calculates any costs. You pay the difference if the new fare is higher, and sometimes a change fee on top depending on the original ticket type.

Flexible fares and higher ones like Plus or Select usually let you move dates with just the fare difference, no extra penalty in many cases. Basic tickets are stricter. Changes often cost more or get blocked after the initial period. Always check the exact rules listed under your booking because they vary by route and how the ticket was sold.

One clear window for no penalty is the first 24 hours after you book direct with the airline. Inside that time you can often cancel fully or switch without fees on most flight-only tickets. After that the normal fare conditions kick in. On short-haul routes some Plus-level tickets also allow a free same-day switch to an earlier or later flight on the same route, as long as you have not checked in yet and give at least an hour notice.

If the tool says the change is free, just confirm and wait for the updated email. Keep a copy of both the old and new details. Bookings made through a travel agent usually need you to contact the agent instead of using the online tool yourself.

Sometimes the available flights look limited at first. Try different nearby dates or refresh the page. If nothing workable appears online the phone line can help, though it may add a small service charge that the website avoids. Make any changes before the original departure or the ticket value can disappear.

That is the core process for most voluntary changes. Rules shift a bit by cabin and origin so double-check inside Manage My Booking for your specific ticket before you finalise anything.

Air Service Hub is an independent information website and is not affiliated with British Airways. The airline name is used only to identify the carrier this guide refers to. To change, cancel or get a refund on a booking, use the airline’s official website or app, or contact the agency where you booked. Fare rules change often, so always check the current conditions of your ticket.
