Sometimes I've been hit by these things based on some kind of automated identity confusion issue and even the attempt to correct the info on the kiosks doesn't seem to stick. Bringing that up to the CBP at the time of entering a US POE has sometimes resulted in "don't worry about it" and sometimes a manual adjustment with some identity-related validating questions.

You clear immigration in GUM, and customs in HNL.

So on arrival in GUM, your passport is checked.

On arrival in HNL, you turn in the customs form. This is where you provide CPB an arriving flight number, and that flight number would be your flight arriving into HNL.

So, when using Global Entry in GUM, you're doing two steps - automatically verifying your passport for immigration purposes, and electronically filling out your customs form for customs purposes.

As you wouldn't give CPB your ICN-GUM flight number were you not GE, providing your GUM-HNL flight number, as the GE station defaulted to, is almost certainly the right answer.

That the person is flying to HNL rather than merely to Guam means that the potential duties due are different. That the person may acquire things in Guam and brings it to the US 50 that are subject to US duty means that the U.S. CBP actually may need to calculate things differently based on the GUM-HNL flight number than on the ICN-GUM flight number.

Raehl311's way of thinking of what to do/leave makes sense, as it sounds like the CBP auto populated at least from a flight booked by/for the OP. [My situation type shared in my prior post have been more complex and are distinct from what the OP experienced, so ignore that post.]

I knew that was incorrect, and answered NO. Took my slip with the big X to the GE line CBP person and told him the flight number was wrong. He found me in the computer on the manifest and said OK. I asked him if it happened in the future, should I say Yes because the city pair was correct, or answer NO because the flight number was wrong.

He told me to answer NO in the future.
