Yes, under current airline treaties it's actually more complicated and takes longer to fly mainland US to Guam, than mainland US to the Philippines. Even though Guam is only a short 1500ml from the Philippines, and:

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...

This is because of 'cabotage' rules, where foreign carriers aren't allowed to sell tickets between two domestic destinations, and except for EU carriers flying within EU countries, this is standard practice all over the world.

Qantas has historically had a similar stop in LAX en route to JFK, although new aircraft will allow them to start making the trip non-stop, in an initiative called 'project sunrise.' [1] I believe they are currently routing that flight with a stop in Auckland as QF3, although they are running AKL-JFK as a 5th freedom with pick-up rights in AKL.

I don't think it's true that it's faster to get to Philippines than Guam from the mainland - you just have to transit in Honolulu. SFO-HNL-GUM on United is 14h15, whereas the non-stop SFO-MNL is 14h35. Philippines only offers limited non-stop options to Manila - just LAX, SFO and JFK - so much of the time you'd be connecting either way, and that eliminates any advantages. After all, Honolulu is pretty much on the way to Guam based on the great circle arc. [2]

What if you had a medical emergency while on the tarmac in Guam?

[arcticbull]

Same as if there was a medical emergency anywhere along the flight path. The plane pulls into the nearest gate where you'd be looked after and you get off. The prohibition is on transporting passengers between two domestic points as a single flight or as a single ticket / with stops under 24h - but note that there's nothing to stop you for instance buying a ticket from SFO-NRT and then a separate NRT-GUM ticket both on ANA.

Cabotage is also referred to as the 9th air freedom, for the curious. [1]

The prohibition on cabotage also applies to passenger and cargo ships. [2]

I'm sure they'd treat you locally (I wonder if air-rage cases get dropped there unscheduled, too, although I don't think so). It's not like the border is hermetically sealed; just disembarking on those particular flights is not available to passengers or skiplaggers. (To be clear, that's because it's a non-US (Philippine Airlines) flight on a technical stopover in a US territory (Guam)). The limitation is purely legal. The airline treaties distort pricing and competition, otherwise it should be possible to do a 24/48h stopover in Guam, Taipei etc., and even lower your overall ticket price if you're flexible about dates.

If not, a creative itinerary with multiple stopovers like Manila-Guam-Honolulu-Anchorage-Seattle could be interesting.

[arcticbull]

If you're looking for 'cool itineraries that end in Guam' there's nothing more interesting IMO than the United Island Hopper, a single flight number with 5 stops operated by a 737. Service is between Honolulu and Guam, taking around 14-16 hours, with stops in:

- Majuro in the Marshall Islands (MAJ)

- Kwajalein Atoll in the Marshall Islands (KWA)

- Kosrae in the Federated States of Micronesia (KSA)

- Pohnpei in the Federated States of Micronesia (PNI)

- Chuuk in the Federated States of Micronesia (TKK)

I believe passengers aren't allowed off in at least one, if not two, of the stops because they're basically just a US military base on a rock. [1, 2]

> The limitation is purely legal. The airline treaties distort pricing and competition, otherwise it should be possible to do a 24/48h stopover in Guam, Taipei etc., and even lower your overall ticket price if you're flexible about dates.

Note that you can do this, it just has to be on separate tickets if connections are under 24h. For a connection over 24h, the world is your oyster, so to speak, from a ticketing perspective. Unless you plan to stay at the airport (and only an option in some places with sterile transit) you may need a visa for the intermediate point.
