Depends how old you are. Big factor in the equation. Under 40, Delta no comparison. Between 40 and 50, tough call. After 50, easy decision, stay at JB, very hard to recover if already a Captain at JB.

Delta has become the airline of the young folks. Close to half of the seniority list has been hired in the last 5-6 years. According to Widget Seniority, had I gone to Delta this year being in mid 40’s, the absolute best I could of hoped for was around 6,500 seniority close to retirement. That buys you dog crap on the Captain side, and that only the last year.
