Same here. I brought a letter from just a captain that I flew with to an interview. I received a letter 4 days later, post-dated the very next day, inviting me to a class. I think it certainly helps because it "puts" another person in the room who is telling the interviewers that you are a good pilot/person. Also try creating a folder of flight awards, accomplishments, WINGS certificates, letters of rec., and a nice copy of your resume. Throw them in plastic sleeves and then into a binder. It starts to make you look organized and impressive.
