In reply to yorkshire_lad2:
Thanks for the updates. Thought I'd update as I went through early on Sunday morning (T2). Queues at security didn't seem too bad, I overheard a uniformed person saying 35 minutes. Checkin to departure lounge was aboutan hour.
What did strike me is the number of passengers that don't seem to be prepared or allow enough time and and therefore have to be "escorted/expedited" by airline staff from coming through security to the gate to get onto the flight. Yes, there are problems with not enough security staff etc but the punters themselves could do a lot to help the situation.
There also seemed to be a fairly relaxed attitude to paperwork (covid test, vaccine cert, etc). Yes, you have to have them, but it was a very cursory check, and it seems the onus is on the airline to ensure compliance, when I arrived in the US, no-one checked any of these documents.
