Bump

Anybody out there with experience or knowledge in how the seniority number at the fapa job fairs work: is that number(e.g. 300) allow you in the door(in order, I guess?) To see ALL the airlines or is the number just allow you to see only one target airline?
My story is that I only care to see UAL.
I guess what I am trying to ask is: that 300 number, does that mean that I'm number 300 in the door and then it's like six flags and I can make a mad dash to get in line for the ride I want(iow run to get in line at the United booth.
Anyone give me a nutshell idea of what exactly that seniority number does? And God-willing UAL does attend, how can I use that seniority number to see them?
