I was thru STN around Mid-day last Tuesday and, having expected the worst, was agreeable surprised. I was hand luggage only and checked in on line so straight to security. slightly surprised that the shoe check is not compulsory! There is a central lane thru which one can walk freely and 2 taped off routes where you get your shoes off and have them Xrayed. Which lane you go thru seems to be a matter of choice! A bit over 5 minutes to get thru and no raising of stress levels at all!
Coming back on Wednesday there was a huge milling crowd at Passport control but, while I was waiting, they opened another 3 checking desks and I was thru in about 10 minutes, this was at about 1730 ie a busy time and beats the stated maximum time of 45 minutes to get processed.
I am thru again in 10 days and, while not looking forward to it, I am not too worried about a stressed up start to a week in Bavaria!
