ATP Written:

Gleim: $20. Test- local lasergrade place with AOPA discount: $70.

FAA Medical: Can't help that, but shop around. I get mine for $75, and my old doc before I moved was $65 (Both for 1st class).

Suit: My $170 JCPenny's (Stanford) suit has served me well and looks just as good as anybody else I've seen in an interview.

Air, Inc: Save your money. Unless of course you just want a bunch of fluff about how good the job is and how hiring is at an all time high.

Professional Resume: Some do- some don't. Personally I've never paid to have my resume done for me. Have some other folks that are in the industry do a once over for you. The truth is that an airline resume is and airline resume is an airline resume. Once you learn the correct format, the rest is easy (it's amazing how many folks don't know the correct format!)

I will ditto what slice says about interview prep...
