Excellent questions, but I can't answer any of them! I would highly recommend paying a company to go over your airlineapps and pilotcredential apps. It's well worth the money and I don't think you can successfully complete these apps unless you pay someone.
I thought I had an extremely good app, until I talked to someone, then realized I wasn't even close. You can either pay the money today, or save your money and pay the money down the road.
I'm sure people get their apps pulled without a consultation, but your future gains are worth the $300 today.
