Long haul, international flying is great. You takeoff, fly until you're hungry, eat until you're tired, sleep until you're hungry again, eat some more, then land. And you're away from the suits and terrible places like Memphis, Houston, Atlanta, Dallas, etc. Plus, unless you're a slam-clicker, there's a lot of neat places to see and equally neat things to do. Nothing beats a 2 hour massage in Shanghi for roughly $7. The downside is the time zones kick your butt and unless you use Skype, it's expensive to call home to get your daily dose of grief from your spouse.

Get both offers, then worry. Otherwise, take the first offer you get. You might not get another one. Good Luck.
