ok, a bit of a weird one.
I booked a business round trip ticket a few weeks ago and did online check in today and paid £398 to upgrade to 1st and got a confirmed seat.
An hour ago AA called me to say there is an equipment change and I'm being refunded my £398 and given a $600 trip credit valid for one year. I obviously wasn't expecting the call and so was a bit cagey on my response as I wasn't sure what rights I'd be giving up here. I asked if this was a UK261 scenario and the rep said yes. At that point we left it there and I'm now back in J on the same out bound flight from LHR tomorrow.
Based on what I can tell this is 75% of the outbound cost (so given it's a £4000 flight, that's likely 75% of 2k), or would there be some weird clause due to it being a last minute upgrade?
