(GUAM) – Flights at Guam International Airport were canceled Sunday and Monday as crews and airlines prepared for Typhoon Bavi, forcing travelers to check their itineraries before heading to the terminal. The airport authority urged passengers to confirm updates directly with their airlines, a warning that applies to both cash tickets and award bookings.

The disruption hit multiple carriers on different timelines. Jeju Air kept Sunday service running, then canceled its Monday flight. United Airlines canceled flights from Sunday through Tuesday. Star Marianas Air suspended operations from Saturday through Tuesday. Micronesian Air Connection Services flew Saturday, had no Sunday flights, and had not decided on Monday service.

The spread of cancellations left Guam travelers with uneven options. Some flights were already pulled from the schedule, while others were still in flux. That meant the safest move was to assume a disruption until an airline confirmed otherwise.

At Guam International Airport, the airport authority’s advice was simple: check directly with the carrier before leaving for the airport.

Typhoon-related cancellations often ripple beyond the first lost departure. A missed inbound flight can knock out the return trip, and a grounded aircraft can leave the next day’s schedule thin as crews and planes are repositioned. United’s three-day cancellation window was the broadest of the group, while Jeju Air’s limited Sunday service gave some travelers a brief opening before Monday’s shutdown.

Award travelers face the same disruption, even if the ticket cost miles instead of cash. No flight means no mileage earning on the canceled segment, and connecting itineraries can lose value fast when one leg disappears. Travelers holding frequent-flyer redemptions should watch for automatic rebooking notices, since some airlines may shift passengers onto later departures without notice.

Rebooking options depend on the airline, route, and seat space available. Flights to and from Guam often have limited frequencies, so a canceled departure can turn into a multi-day delay. That makes same-day reroutes harder than on larger mainland networks, where competing airlines often offer more departures and more open seats.

Passengers with checked bags should keep receipts and tag numbers close at hand. If a flight is canceled before departure, bags are often pulled from the aircraft and routed back to the claim area, but timing depends on the carrier and the airport’s ground operations. Carry-on only travelers usually have the easiest path to a quick change in plans.

Sunday and Monday cancellations also complicate travel planning for people connecting through Guam to other Pacific destinations. Guam serves as a key stop in regional travel, and a three-day pause at one carrier can break onward plans to islands with fewer alternatives. That leaves travelers with less room to improvise than they would have at a major hub with multiple daily departures.

The fastest next step is direct contact with the airline handling the ticket. Passengers should confirm whether the flight is canceled, delayed, or tentatively scheduled, then ask about rebooking before heading back to the airport. With Typhoon Bavi driving the schedule changes, the safest assumption is that additional disruption can continue through Tuesday.
