Sorry, it's BA1679 DFW-LAS on 2/2/22.

That would make sense. A leave it to BA and see what happens? I am meeting people on that flight, theyre connecting from LHR, me from MAD so hopefully both itineraries fix to match. I'm guessing this will be a "Your flight times have changed" and not a "sorry your flights been cancelled, accept these changes."

Appreciate the fast replies.
