I had two potential ones on my flight from LAX, but decided I couldn't be bothered with BA's faux greetings etc. so made it clear not to waste my time.
Usual mess before boarding didn't leave me in a good mood, and the delay carrying on from that.
Then in WT+, managed to get the only seat next to the one infant on the plane (although they were well behaved).
Did get to see a couple of people, possibly from WT, upgraded to CW as well before take-off. Not crew. The girl seemed genuinely excited.
