It was very quick, as there were only 150 people in this job fair. Very small crowd as opposed to the usual 400-500.

My seniority number was in the mid 80's.
They opened the doors at noon.
By 12:15, they were already calling 1-50 numbers.
By 12:20, 1-100.
By 12:30, I had already talked to HR, and was on my way to catch a much earlier flight....

Allegiant and Atlas had the longest lines. (if we can call half a dozen people waiting a long line). A few regional booths had very few "wannabe" and the Asian airlines had absolutely none, to the point that one booth was not even manned after a while.

I would be curious to find out if they stayed open until 5PM, it moved so fast...
