Sky Nazi or Kool Aid drinker? My own opinion is mil guys put too much initial emphasis on atmosphere, not economics or upgrades. Five years into your career you will finally understand nobody in management gives a tinkers damn about you, so go based on:
Long term stability
Domicile options
Upgrade demographics
Type flying
Pay
Why is pay last? It often changes. The other factors can also change but tend to be more static.
International flying is cool for all the reasons indicated. More money, more adventure, more time off. I would go Us Air/AA and never look back.
