I wouldn't base any career decisions on opinions on an anonymous message board!

Make a chart of the pros and cons of each company. TS Inc=possible quick upgrade, but get treated like dirt. Faster career progression. SKW=stagnant but a good place to spend your career if you get stuck. Treated well and paid well.

DON'T base your decision on bases or upgrade times. Things change in an instant in the regional industry. Just because you can be based near your home as a newhire, doesn't mean you won't get displaced to East Jesus in a year and forced to a 3 leg commute. and contracts end. I keep hearing GoJets may not be flying for Delta too much longer. Upgrade times could easily spike. SkyWest is very stable.
