For the second time in three months it won't allow me to check in online! Its soooo annoying when they have such a system that when it works is brilliant but now I have to arrive at Manchester Airport early because of there dodgy online system!!
It's a shame you haven't managed to use OLCI. It may be that you were just unfortunate to be picked out at random for a second time for security reasons.
It can just happen like that but is frustrating none the less.
