If staying on the west coast is your priority, then Delta should be your first choice. SEA and LAX bases. If that’s not an option then unfortunately Alaska is your choice. If career advancement, QOL scheduling, good contract, growth, Pay, retirement then Delta again should be your first choice. If not, then Jet Blue is your choice. If you come to Alaska you can expect a LONG upgrade time, a seriously substandard Reserve schedule, a management group that thinks growth is more RJs at other airlines, a seriously substandard QOL compared to ALL the other major airlines.
