BRU? My experiences there are not very good. Long lines, usually very disorganized (esp. on the non-Schengen pier) scrum - although the lines move surprisingly quickly. Officers are very strict, I've been given the full body pat many many times and pretty much always had to take off my shoes, which kinda sucks. For the Schengen-pier security they do this in the private cabin, and sometimes you have to queue for that.

Hmm. Come to think of it - many tiny airports have the best security experiences. Not too many pax so no big queues, relaxed officers who even have time to joke etc. Although I kinda like ARN T5 (the entrance by the B-pier, the Norra security point is just horrible), RIX (every time it looks like there's a huge queue but actually you're through in 3 minutes) and HEL as well (but the last one probably because I am just too familiar with it and the people there).
