Take the bird in hand! If you don't like it, UAL is a fantastic place to work too. Perhaps a bit more opportunity in ATL with all the fleets, instructor gigs/other spend more nights at home opportunities. Retirement numbers aren't that far off. Current UAL management seems to be bigger on hiring than our current management, though that comes with its own pros and cons. You can't go wrong, but whatever you do, don't turn down a seniority number here when you don't have a class date elsewhere yet.
