Very good at Leeds Bradford when I flew to Spain last year
Worst by miles, and not just UK but everywhere Ive been to is Manchester
Over 2 hours waiting in a queue for hand luggage inspection on Christmas day this year, 2 out of 6 machines working one person fainted and one was sick whilst stood in line waiting. on asking the staff what had happened they said simply lots of staff had not turned in. Complete farce, treated like cattle rather than customers.
that was the worst Ive ever had, however Manchester always had long waits, in fact it doesn't matter what time you arrive as if your flight is leaving in the next 10 minutes you always have to hold your hand up in the line so you can be brought to the front of the queue, so you might just as well not even get in the line until 20 mins before the flight is due to depart.
