Philippine Airlines flights from west-coast US (SF, LA) refuel in Guam, since a 2006 "technical stop" agreement [0] (not allowed to pick up passengers on Guam, but can refuel and pick up supplies); at least during the winter headwinds, Nov-Mar [1]. Passengers can't even get out of the plane, you get to sit on the tarmac and watch the fuel tankers out the window for 45min in the predawn. I wanted to at least get out and see the inside of the terminal but absolutely not. ("Guam: the ultimate skiplagged challenge")
So you won't see this arrangement show up on any ticket engines, and they're not allowed say "Philippine Airlines flies to Guam". Are there any good articles on how current airline treaties affect routes and pricing in the Pacific?

[1]: "The one-hour technical stops are required during certain times of the year, particularly during the winter months of November to March, when headwinds are strong enough to affect aircraft flying westward across the Pacific." (to avoid exceeding MTOW)

I'm sure Gordon Lightfoot (RIP) could have sung about treaties...
