Not too long ago, CAI-LHR on BA. Husband and I had 62J/K on UD and got upgraded to 2A/K . First upgrade for the OT having been a gold card holder for about 8 years.

Sadly 2A was broken. The seat couldn't go fully flat and the footrest wasn't working at all, and there was no other seat I could move to in F as it was full. Fortunately the flight was about 4 hrs so I pretty much put up with it.
