I was one of the last new hires to get Guam (almost 2 years ago). It's pretty senior now, as more folks from L-UAL are coming out here. The $3000 is taxed as income, so the net is about $1500-1700, and the rest is more than eaten up by the cost of living. The main contractual advantages have been listed, except for the paid moves, and those need to be handled judiciously, as the penalty for leaving early is quite steep.

If you have kids, you need to think twice. The schools here are awful, and not everybody is cut out to home-school.

If you have the right personality, it's a great base. I have no desire to return to domestic flying.
