On waitlist
If you tried to FOC but didn't get it confirmed then you should be on the waitlist. The waitlist is not the same as being listed though! Last time I was lucky enough to find someone at check in who knew the system, it still took them ages to transfer our details from one part of the system to another. Meanwhile other Staff with lower priority were getting seats.
How a company can try and skimp on IT in this day and age I do not understand.
