Lot of nonrevs go on that route for some reason.

10AUG has 29 seats, 44 nonrevs
11AUG has 93 seats, 42 nonrevs
12AUG has 114 seats, 25 nonrevs

Anything to SEA would require a stop in SFO, LAX, DEN, or something further east. If you can, I'd suggest meeting her in HNL (or just sending her through on her own if that's an option).

Don't forget that this flight crosses the international date line, and leaves somewhat early from GUM, so you actually arrive the day before you leave. Cool, huh?
