Guam is about as far west as the United States goes. The island sits in the Western Pacific, closer to Tokyo and Manila than to Honolulu, with warm water all year, the hotel strip along Tumon Bay and a Chamorro culture all its own. It is also US soil, so you will use dollars, hear English everywhere and travel domestically, even if it is a long trip. Flights from USA to Guam all land at Antonio B. Won Pat International Airport (GUM), and most go through Honolulu. FaresMatch lets you compare those routes and fares in one search, without stitching the trip together yourself.
Find Cheap Flights from the US to Guam
Guam is a long way from anywhere, so fares are rarely low, which makes comparing even more important. The same trip can cost hundreds of dollars more or less depending on the airline, the connection and the day you fly. On FaresMatchyou see live fares side by side, so the gaps are obvious.
Flexible dates help a lot. Christmas, New Year and the summer school break fill up first and cost the most, so leaving a few days earlier or later can make a real difference.
Compare one-way and round-trip fares too. A round-trip on one airline is usually simplest and often cheapest, but two one-way tickets sometimes work out better. If you book separate tickets, leave plenty of time between flights, because the second airline doesn’t have to wait if the first runs late.
Check other departure airports as well. On the West Coast, Los Angeles and San Francisco often price differently. And on a journey this long you will probably check a bag, so look at baggage allowances and change rules before you choose. We show those details before you pay, which makes it easier to find genuinely cheap flights to Guam from USA, not just a low headline price.
Which Airlines Fly from the US to Guam?
United Airlines is the only airline flying nonstop between the US and Guam. Other airlines can still be part of your trip by getting you to Honolulu or an Asian hub, so check which legs each airline actually flies.
United Airlines
United runs the daily Honolulu nonstop, the Island Hopper and flights from Guam to Japan and other parts of Asia. For most travellers, it flies at least the final leg into GUM.
Hawaiian Airlines
Hawaiian, now part of Alaska Air Group, does not run scheduled flights to Guam, but it can get you from the mainland to Honolulu to connect with United.
Alaska Airlines
Alaska flies to Honolulu from many West Coast cities, covering the first part of the trip before United takes you on to Guam.
American Airlines
Americans do not fly to Guam itself. It can get you to Honolulu, or to Tokyo, where its partner Japan Airlines flies on to Guam.
Delta Air Lines
Delta does not serve Guam either. It flies to Honolulu and Seoul, and from Seoul its partner Korean Air flies to Guam.
If a trip mixes airlines, booking it on one ticket is usually safer, because the airline then has to rebook you if a delay makes you miss a connection.
