Gloopy..... I totally agree with you. I have done all three, 121,135, and 91. I'm currently at a fortune 500 dpt and am trying to get on with a major. DL is at the top of my list. I have 10 internal recs and one from an EVP there. Still no love!
The stereotype for the airline vs corporate thing drives me bat-sh!t crazy! Its all about the individual IMO.
