In late spring 2012, I arrived at the terminal around 5:45 am for a 7 am flight, and found it took over an hour from joining the queue near the check-in desks to clearing the security hall - it took about 30 mins in the queue just to reach the bottom of the main staircase. At the time, I recall all security lanes open and staff advised it was quite normal with no particular systems failure on the day. I recall also Ryanair passengers being told to use a separate gate for screening.
I know Luton airport has a history of underinvestment, but does this kind of queue length still occur, or has the root cause of 1+ hour delays now been solved ? Luton is my local airport and I prefer to use it if possible, but wondering if I need to choose an alternate London airport to avoid being treated like s--t
