Was on BA 2794 LGW-AGP today.1 min check in and lovely quiet lounge. Left lounge when the screen showed we were boarding at gate 91- sounded a long way but was only 2 minutes and of course we weren’t boarding. Priority boarding strictly enforced only to find it was a bus gate. Still done very quickly we then had a reasonable bus journey felt like 5-10 minutes to stand 177. However boarding , crew , drinks service , meal service all done very well. I think you would have to know the minutae to spot the difference between this and a LHR CE flight. To me it felt no different. Excellent job by flight and cabin crew.
