Did the Jet Time LHR-CPH.
Twas also my first Gate 10 for months.
The flight was okay, seat width felt tight as 12B was closer than the middle seater would normally be.
12A and 12F have fantastic legroom and full windows. I was happy enough in 12A, albeit the BA ET seat is more comfortable (for me).
Club looked a bit miserable ... what with the middle seats left clear but barely anything else to convey the premium cabin.

Of course, its Jet Time staff operating to BA scripts ... but without the flexibility BA cabin crew provide. Possibly, a wee enhanced procedure on catering too.
No sticky bun! and ..
.. my normal cheery request for a second mixer can was met with a "just one" for the first time ever on BA. I must have pulled a surprised face as she relented and passed a second can a few seconds later. A couple of rows back others were not so lucky.

All-in-all, not awful, not great. I'll probably avoid from now on where I'm in anything like a 50:50 on flight choices.
