Flew into Birmingham last night from Alicante with Ryanair.
When we landed we were told in no uncertain terms to stay seated and to stand up and collect our overhead luggage row by row and leave the plane. Surprisingly everyone did as they were told.
We were greeted by two people from border control who asked to see your locator form. You either handed in a printed one or showed a downloaded copy on your phone and walked straight through to passports OR.... joined the 60-70% of people who hadn't done it and filled one in on the spot before you were allowed to pass.
BHX was deserted a very sad site.
In Alicante when we arrived 10 days ago it was passports first, then a temperature check via overhead cameras and finally scan the locator form at security before leaving the terminal.
It seemed to work well at both ends.
