I have a couple questions around CJOs; I understand most pilots interview with a couple different regionals accepting multiple CJOs. I recently interviewed and was told (verbally, and follow up congratulations email) I passed the interview and they would let me know about class dates. I suppose that's a CJO? When are you officially committed to that airline? When you accept a class date, month before class, etc? I guess I'm looking for some guidance as to when that airline assumes you are going to them. I have not interviewed anywhere else but there is one other airline that would be my first choice if they called. I want to make sure I'm doing everything on the up and up and not burning any bridges if I decide to go to another airline.

Thanks!
