I'm afraid it is also normal for BA never to call you back about it

; there seems to be quite a big hole in BA's systems here and it is pretty disgraceful.
I'm pretty sure they can actually tell that your ticket is for the flight you originally booked and not (yet) the other one, even if this isn't apparent in MMB.
This is right - the 'new' flight appears in MMB, but they don't actually re-issue the ticket until ticketing have looked at it, so the only flights you can actually check-in for/fly are the 'old' flights (because the tickets still exist). The 'new' flight is only really locked in the reservations system, to stop it being re-sold.
It is driving me absolutely mad trying to get BA to call me back about a change of this nature. I have a flight on Satuday, so OLCI tomorrow, where (despite calling 3 weeks ago) I
still haven't been called back. And on each of the two times I've called to chase, I am told that it is in the queue, that if they touch the entry in the queue it will go to the back of the queue, and all they can say is that I will definitely be called...!
What's the point of having a fully flexible ticket if you can't actually change the damn thing.
