Chuckie,

LOR's are extremely important. Every airline has a different process on how they view a LOR, but they all look at them. AA doesn't look at the recs until you interview for example, but others are submitted internally. LOR's paint a picture of you by your peers.

If I could give you one piece of advise it's this: Proof read and approve your LOR before it's submitted. You'd be shocked at how many LOR's I read that are submitted to XYZ airline that have spelling errors, punctuation issues, fragmented sentences, etc. It's the little things that matter so make sure it doesn't look like a 3rd grader wrote the LOR on your behalf. Have the letters personalized to the specific airline as well.

Hope this helps.
