By plane
Won Pat Guam International Airport (GUM) is the only civilian gateway to the island.
The airline servicing Guam is Continental Micronesia or Air Micronesia (as formerly known), a branch of Continental Airlines, which offers non-stop service to Honolulu with onward connections in Honolulu to Los Angeles, Newark, and Houston. It also offers non-stop flights from Guam to Cairns in Australia, as well as most major cities in Japan, Palau, Manila and Cebu in the Philippines, and many of the Federated States of Micronesia.
All other service to Guam is through East Asia on Northwest and JAL (both serving Tokyo, Osaka and Nagoya), Korean Air (Seoul), ANA (Osaka), China Airlines (Taipei) and Philippine Airlines (Manila).
By boat
There is no regular ferry service from Guam, but cruise ships do stop in Guam on various itineraries, generally as part of a Pacific crossing or world circumnavigation.
