As far as the fast pass goes:
If you don't meet the minimums then stop wasting everyone's time...you want to learn about their company? Then go to their hiring briefs.
The airlines are pretty clear about what the eligibility requirements are for a fast pass.

Job fairs are BS in a way. I learned so much by going, and I am glad I did. However, I'd bet in 6 or 7 years the airlines won't care if you went. In a cold hiring environment you have to do whatever it takes.
