Most important tips

Know before you go

A compact traveler cheat sheet for timing, terminals, food, and disruption checks.

Timing

Both lounges close in the afternoon

United Club temporary hours end at 1:00 p.m. Sagan Bisita’s airport page ends the second session at 5:00 p.m.

Priority Pass prints 23:00–17:00 with no gap. The airport page prints 23:30–11:30 and 12:30–17:00. An evening departure can miss both rooms.

Terminal

Arrivals stay off the departure concourse

Foreign arrivals use the third-floor corridor and go to U.S. Customs and Border Protection.

The corridor opened on 25 January 2022. Guam is outside the customs territory of the 50 states, so a Honolulu connection is not a domestic arrival.

Food

The buffet is inside Sagan Bisita

The airport page describes a hot and cold buffet and free Wi-Fi there. It does not publish a restaurant list or prices.

No bottled-water price and no fountain map were on the GIAA pages checked on 24 September 2026.

Status

Field is open; typhoons are the pattern

FAA attendance is continuous. No closure was confirmed on 24 September 2026.

The May 2026 GIAA newsletter said Customs-hall and baggage-claim flooring, damaged by Typhoon Mawar, was scheduled through 5 June 2026. That date has passed. On-time performance is not published.

Live conditions

Security waits and operational status from official feeds, where the airport publishes them.

Honest verdict

Who this airport works for

Best for

A morning United or Japan connection
Priority Pass before 5:00 p.m.
A short taxi ride into Tamuning

Watch out for

United Club hours that still end at 1:00 p.m.
Sagan Bisita’s airport hours and Priority Pass hours do not match
No airport railway and no published taxi fare
Typhoon closures; on-time data is not published

Match the lounge clock to your departure. The airport page prints Sagan Bisita as 23:30–11:30 and 12:30–17:00. Priority Pass prints 23:00–17:00 every day with no midday gap. The United Club page still says temporary hours of 4:30 a.m. to 1:00 p.m. An evening departure can miss both rooms.
