This is a very trivial issue I guess but I just 10 spent minutes trying to get to the right floor for A380 economy class boarding direct from the lounge. The level one button didn't work and we were forced to get out on the second floor. We then weren't able to call a lift to go back up or down! Eventually we ended up in the first class lounge where a staff member was able to use their pass to take us to the right floor.
This is the third or fourth time this happened to me and I'm wondering whether anyone else has ever had this problem?
