This is a great question because it reflects my actual experience.
In 1990 when I was getting out of the Navy, UPS was just spooling up. You didn't even need to go to Louisville for an interview because they were setting up recruiters in hotel rooms near the major military facilities.
I interviewed at Alaska and got the CJO. When I got home I was supposed to go over and see the UPS recruiter. However, at the time, senior AS Captains were at $154 an hour and UPS on every fleet paid $111 an hour. I didn't even go see the recruiter and took the AS job.
20 years later I was making $200 an hour and as a widebody UPS Captain I would have been making 1/3rd more. Going to AS over UPS was the biggest career mistake I ever made. I don't even want to think about how much money it cost me.
Redeyes? You'll have your fill at both operations, but after having flown widebody aircraft you don't want to be stuck on the 737 West Coast's most popular regional airline for your career. International is the way to go.
Choose wisely.
