If you are at UPS for stability there is almost no other place to be unless you are in the bottom 600. The problem with a career at UPS has to do with negative growth for the foreseeable future and little retirements for the the next 20 years. Most mature airlines have about 5% of their pilots retire per year. When retirements start again in a couple of years UPS retirements will be around 1-3 % per year. Couple that with the shrinkage of flying equals stagnation. Don't get me wrong, compared to almost anywhere else you could be UPS is at or near the top, but most guys hired in the past 10 years are looking at a 20 years until upgrade which isn't that great because the average age of new hires in the past few years has been around 40.
