I wanted this to be a few live comments so just one brief reply about queues.
On entering the terminal from the open concourse there was a queue extending about two thirds along to enter the main departure building. In width it occupied half the walkway; the travellator was not working and cordoned off. Being England everyone joined it, the great and the good as well as the first time flyer! Staff were walking along the queue telling those who had not checked in to skip the queue and walk straight in. So, if you were a GGL for life Prem who had checked in you queued but if you were making your first ever flight to Benidorm, and were wondering what check in was and how you put your six cases into the aeroplane’s boot, you skipped that queue
Once inside the departure building small signs directed Gold/Silver/F/J passengers to those check ins. Within that area further signs and tensa barriers separated sheep from goats. The goat queue was moving much faster than the sheep queue!
I know nothing of Y/Bronze/Blue check in.
