I got extremely lucky and recently got a CJO with Delta & American, one week apart. I never thought I'd be in this position to have the option but need to make a decision soon. I will likely be commuting from STL, which neither airline has a crew base, so that's not much of a factor at the moment. Main deciding factors are QOL / days off, commutability, and employee morale. Any advice or opinions are very much appreciated.
