Inside the airport

Lotte Duty Free, a food court, and the Sagan Bisita Lounge (paid or Priority Pass) are the main in-terminal options.

No nap pods or transit hotel exist in the terminal; the Lotte Hotel and Westin in Tumon, about 5 minutes away, offer shuttles and are the recommended overnight option.

US citizens need no visa, as Guam is a US territory. International travelers generally need valid US entry documents (ESTA or a visa); separately, a narrower Guam-CNMI Visa Waiver Program covers 12 specific nationalities for up to 45 days, but since 29 November 2024 this requires an online Electronic Travel Authorization applied for in advance, with travel direct to Guam/CNMI. All arriving passengers must also complete Guam's Electronic Declaration Form up to 72 hours ahead (electronic-only since 4 February 2025, with kiosks available on arrival as a backup).
Transit visa requirements vary by nationality and change frequently. Always verify with the official embassy or consulate of Guam before travel.
