I've been doing Guam a lot lately. Most of the time, there are a few seats, meaning less than 10 open, out of 360, going. Not weight restricted ever going.

Coming back however is a different story. I don't know what they will do once the P&W planes come back, it used to be a 777A, restricted all the time. Now we are using the 777-300ER's. 2 times recently weight restricted due to massive amounts of cargo from HKG flights--we left people behind. My last flight was not restricted, but volumed out on cargo so we were able to take all the passengers. But we were still within 5K of Max 0 fuel wt and landing weight. The wt restrictions have been max 0 fuel weight. A jump seater is not restricted on those flights as it is included in the operating empty weight of the plane.
