My positioning flight have _all_ changed. I am staying overnight, so no worries there.
I've set up an account with CheckMyTrip, and it seems to have been the fastest to notify me. Even faster than BA updating MMB.

MyFlights is a free alternative, if you have an iOS device.
However it cannot query AA reservations (although if you booked via BA, it can see the AA reservations through the BA system).
