I had a mixed experience travelling through T1 at the start of September. Security was definitely the pinch point in terms of social distancing. This wasn’t helped by the fact all passengers were using the Jet2 security area (a first and hopefully last for me) which was cramped and reminiscent of a basement car park.
Much better in the main body of the terminal with proper management of queuing at the food outlets.
Departure gate (11) was dreadful with no attempts to manage the boarding process in an orderly way.
Return the following week was also the worst experience in a while. An hour from landing to collecting bags, mainly due to a ten minute wait for an air bridge and a big queue for border control.
Last point on social distancing. Masks were worn by pretty much everyone (though not always correctly) which does mitigate some of the social distancing issues. Plenty of hand sanitizer stations too, though disappointing number of people not bothering to use them!
