Airlineapps says comair does not require an ATP written, I have to agree with whoever on here posted, that the regionals are lower their requirements not tightening up on them. I know several people flying the line without it.....They do want it before upgrade JUST so they dont have to pay for it.... This was told me by one of the recruiters ( a Captain) AT our interview..... Also when we were about 2 weeks into class they told us to bring all of our certificates and medicals, when we asked if to bring the writtens they laughed and were like KEEP THAT IN A SAFE PLACE TIL YOU UPGRADE........ your decision though
