Endeavor, Republic, Skywest, Envoy, compass...
I've been out of the regional world for a few years now, so perhaps with new contracts things have changed as to who is best. Just know that bad reputations last forever. The Capt I had on this last trip (Delta 757/767) commented when we passed Gojet on the ramp in DTW that he was Jumpseat chair for Delta in 2007 and it gave him pleasure to tell the Gojet Jumpseat coordinator to pound sand when they asked for a reciprocal Jumpseat agreement. (They ended up getting one via the Northwest merger years later)....but this Capt still dislikes Gojets 11 years later, who will be on your hiring committee when you go to a major?
