Hey travel buffs, ever realized you added the wrong frequent flyer number to your British Airways booking, or maybe you joined the Executive Club after booking and want to switch to earn those sweet Avios points? I’ve been there—on a flight to London, I accidentally linked my old AAdvantage number instead of my new BA Executive Club one, and I scrambled to fix it. Changing your frequent flyer number on a BA booking is totally doable, but the process depends on your booking and timing. Let’s break it down for 2025 with easy steps to keep your miles flowing. If you hit a snag, just call 844-928-0428—they’re fantastic at sorting out these details.
If you’re managing a booking made directly with British Airways, the easiest way to change your frequent flyer number is through “Manage My Booking” on ba.com or the BA app. Log in using your six-character booking reference (PNR) and last name, then head to the passenger details section. You’ll find an option to update or replace your frequent flyer number, whether it’s for BA’s Executive Club or an One world partner like American Airlines AAdvantage. I fixed my mix-up this way for a trip to Paris, and the new number was linked in seconds. Make sure the name on the booking matches the frequent flyer account exactly to avoid issues.
If you booked through a travel agent or third-party site, things can get a bit trickier. Some agents don’t forward updated frequent flyer details to BA, so you’ll need to log into “Manage My Booking” on ba.com to make the change yourself. If the BA site doesn’t recognize your PNR (common with third-party bookings), contact the agent first, but BA’s team at 844-928-0428 can often help by pulling up your booking with your flight details. I had this issue with a Kayak-booked flight once, and a quick call to 844-928-0428 got my Executive Club number added without a hitch.
For codeshare flights—say, BA marketed but operated by a partner like Qatar Airways—you might need to update the number with the operating airline’s system, especially if miles are credited there. Check both BA’s and the partner’s website, and ensure the name matches across all systems. If you’re switching between One world programs (e.g., from AAdvantage to Avios), confirm the new program accepts credits for your flight class. Calling 844-928-0428 can clarify which airline handles the mileage credit for codeshares.
If you’ve already flown, you can still change or add a frequent flyer number to claim missing Avios or miles, typically within six months of travel. Go to the Executive Club section on ba.com, select “Claim Missing Avios,” and submit your ticket number or booking details. I forgot to add my number on a short-hop to Dublin once, and claiming it later was easy—points posted in a week “Claim Missing Avios.” For partner programs, follow their claim process, but 844-928-0428 can assist if BA’s system is involved.
Timing matters—update your number before check-in to ensure miles post automatically. For group bookings, each traveler’s number needs to be updated individually, even in a Household Account. Pro tip: Double-check your number in “Manage My Booking” a few days before flying to avoid surprises. In 2025, BA’s digital tools make this process smooth, but phone support shines for complex cases like codeshares or post-travel claims.
Changing your frequent flyer number keeps your rewards on track, whether you’re chasing Avios for a reward flight or miles for status. Ready to update your BA booking? Call 844-928-0428 now to ensure your frequent flyer number is set and start racking up those points!
