Ive been following this thread was some interest as I'm on BA0106 02:20 Mon 13 Dec 2021.

I picked this flight on purpose based on BA bringing back the a380 and the availability of first (for about 10minutes) when the flights were loaded in the system.
.
The 2.20am flight allows me to watch the end of the F1 race in Abu Dhabi - maybe have a quick drink at the track, jump in a taxi, then on a plane and do some work Monday in London (hopefully).

I'm HBO and was hoping to be able to check in online and arrive at airport 90mins before departure (circa 01:00).

Is this a safe arrival time? Will online check-in work OK from DXB-LHR?
