You get international override on each leg with Guam. Also several scheduling provisions allow you to compress both lines and reserve. Other smaller things, but not worth mentioning. Best perk is Guam flying is prob the easiest and most productive narrow body flying a US Guy can get.

That said previous post is correct. Guam is prob an unlikely new hire destination for the forseeable future. Vacancies are a trickle and usually get snapped up by somebody who has been around a few years.
