I would def pick a wholly owned regional right now.. Some day United will learn as their feed will start to dry up and it will be impossible to staff places like XJT, TSA or even Mesa because more and more people are looking for that legacy seniority number for career progression. Not only are places like PSA, Envoy, Piedmont owned by AA they have bonuses for new hires, also with the amount of retirements over the coming years flows won't be as bad as the past because it will move along alot quicker with those retirements at AA Its really a no brainer at this point.
