Pros
The flight benefits are about it really. Aside from that, there is that collective culture that everyone tries to help.
Cons
The 1300 hour limit for ready reserves makes it tricky to swap shifts when you need to, and is still counted against you when they freeze your schedule during irregular operations (i.e. severe weather). At the same time, doubling up seems to be easier to do in some of the hubs like Atlanta, Minneapolis, Detroit, etc despite some bases having high seniority, making it harder to work your way up. If you want to move up in the company, then you'd have to be open to relocating. Your shifts fluctuate about every six months when you bid again based on seniority, so over time it does provide more flexibility in your daily life if you choose to stick it out.
