Quick summary
On 6 July 2026 Super Typhoon Bavi canceled every flight into and out of the Northern Mariana Islands and closed all three CNMI seaports; Guam alone lost 44 flights, 23 departures and 21 arrivals. A 2 July 2026 airport update says airlines often decide inside a 24-hour window on short-haul flights.
Airports stayed open while nothing flew, and port restrictions outlasted the winds. Here is how Micronesia typhoon season flight cancellations actually unfold, and how to build an itinerary that survives them.
On 6 July 2026 the eye of Super Typhoon Bavi passed directly over Rota. The Northern Marianas stopped moving.
Two details from that week matter more than the headline winds. An open airport did not mean an operating flight. And short-haul cancellation decisions left little warning. For anyone flying in from North America, Europe or Australia, that leaves almost no time to react.
2026 did not fit a neat season. Sinlaku hit Saipan as a Category 4 storm in April, and Choi-wan briefly reached super typhoon strength on 5 October. With Bavi between them, three systems in three different months made itinerary design more important than picking a safe week.
What typhoon season does to Micronesia flights
Bavi was the ninth typhoon of the 2026 season. It carried a central pressure near 910 hPa and winds of roughly 201 km/h when Korea’s meteorological administration tracked it on 7 July, as Seoul Economic Daily reported.
Guam’s Joint Information Center put the storm’s peak winds at 180 mph. Weathernews counted more than 1,200 flights delayed or scrapped across Asia during it.
At A.B. Won Pat International, six carriers lost flights on 6 July 2026: United Airlines, Korean Air, Jin Air, Air Seoul, Philippine Airlines and Star Marianas Air. Korean Air canceled its Incheon to Guam service outright. The cancellation lists also reached Tokyo, Manila and Koror. A storm over the Marianas rearranged travel plans in four other countries.
A bad week reaches beyond one airline or island: the hub goes quiet at the same moment as the inter-island network.

How far ahead airlines cancel flights
The notice is shorter than most travelers assume. In a 2 July 2026 update, the Guam airport authority said airlines often make decisions within a 24-hour window for short-haul flights.
Bavi’s carrier-by-carrier response shows how tight that window is. United suspended operations from 5 to 7 July. Jeju Air canceled its 6 July flight after operating on Sunday, then had no operations at all on 7 and 8 July.
Star Marianas Air suspended flights from Saturday through Tuesday. Only Micronesian Air Connection Services kept anything on the ground moving: it operated Saturday, flew nothing Sunday, and left Monday’s schedule tentative.
Recovery is slow because the schedule is thin. Guam airport advisories note that rebooking depends on the airline, the route and seat availability, and that limited flight frequencies can stretch a delay well past the weather itself. Short notice and few spare seats can turn a two-day system into a four-day stranding.
Which airports and ports stay open
Terminals in this region tend to stay open even when flights stop. On 6 July 2026, Saipan, Rota and Tinian airports remained open as facilities while every flight was canceled and the terminals were closed to passengers. Guam’s A.B. Won Pat International Airport ran 24/7 through Bavi with operations disrupted.
Ports run on a different clock. Berthing was not permitted at Rota West Harbor or the Port of Tinian until Bavi had left the CNMI, and the Port of Saipan closed for operations. When Sinlaku approached in April 2026, every CNMI seaport moved to Port Heavy Weather Condition Yankee, which bars vessel or port entry. A flight can resume while the boat leg of the same trip is still shut.
Storm damage can outlast the storm too. A notice to airmen kept Saipan International closed to normal Part 121 operations until at least 30 April 2026, with daylight-only operations permitted, power coming from generators and limited running water. Tinian was restricted to lighter aircraft and daylight rescue flights, while Rota stayed fully operational.
When your Micronesia flight is disrupted
During the 6 July 2026 port update, FEMA was already planning cargo charters and waterborne shipments of generators and meals, contingent on runways and harbors being usable afterwards. When relief logistics are waiting on the runway, a passenger rebooking sits behind them.
The fragile link is the inter-island network. Star Marianas Air and Micronesian Air Connection Services fly the short hops, and both were grounded by Bavi. Miss one of those legs and the next seat may be days away, on an aircraft that has since been repositioned. Trips that continue west to Chuuk or Yap carry a second, separate question about medical evacuation, which our guide to the cover Micronesia dive trips actually need sets out.
Choi-wan is the reassuring case. It peaked near 135 knots on 5 October 2026 before turning north and away. All Marianas watches and warnings ended, and Guam’s airport stayed open with most scheduled flights operating. But a Small Craft Advisory remained in effect through the following Tuesday afternoon: the marine half of a trip can stay hazardous long after the airports have gone back to normal.
Rebook inside the 24-hour window
The help has to be in place before the alert arrives. Guam’s airport authority and the island’s joint information center both tell travelers to confirm status with the airline directly. If a system is still tracking toward the Marianas, act the hour a notification lands.
- Add a spare day at Guam: build the buffer into the long-haul leg rather than the island leg; our page comparing flight options to Micronesia from North America shows where those connections sit.
- Read the natural-disaster wording: check before you pay whether a weather-cancellation loss is covered at all, and store the policy number somewhere that works offline.
- Ask which harbor your boat leg uses: a Port Heavy Weather Condition or a closed port can outlast the flights by days.
- Watch: Small Craft Advisories. They are the clearest signal that the marine half of a trip is still down.
Sinlaku landed in a month few travelers think to circle in the calendar, and the damaged airport took weeks to recover. The itinerary that survives 2027 has slack on both sides of the Guam connection and a rebooking plan you can execute from a phone.

When is the highest-risk period for Micronesia travel?
The 2026 record argues against a single peak. Sinlaku struck Saipan as a Category 4 storm in April, Bavi shut the CNMI in July, and Choi-wan reached super typhoon strength in October. Airlines react on a rolling basis rather than a seasonal one: the Guam airport authority’s July 2026 guidance has carriers deciding inside a 24-hour window on short-haul flights, so your buffer matters more than your month.
Can airplanes fly during a typhoon?
Whether a terminal is open tells you nothing about whether flights will operate. On 6 July 2026, Saipan, Rota and Tinian airports stayed open as facilities while every flight was canceled and terminals were closed to passengers, and Guam’s airport ran around the clock with 44 flights canceled. The decision sits with the airline and the storm’s track, not with the airport’s doors.
Which airline flies to Micronesia?
On the day Bavi hit Guam, the six carriers with cancellations were United Airlines, Korean Air, Jin Air, Air Seoul, Philippine Airlines and Star Marianas Air, and Korean Air canceled its Incheon to Guam service. The short inter-island hops are flown by Star Marianas Air and Micronesian Air Connection Services, both of which were grounded during the storm.
What happens to port-based plans during a storm?
Ports close before the strongest winds and reopen after them. During Bavi, berthing was barred at Rota West Harbor and the Port of Tinian while the Port of Saipan closed for operations; as Sinlaku approached, all CNMI seaports went to Port Heavy Weather Condition Yankee. Marine advisories can linger after flights restart: a Small Craft Advisory was still in force after Choi-wan’s watches ended on 5 October 2026.
What did airlines actually do when Bavi hit?
They stopped flying rather than rerouting. United suspended operations from 5 to 7 July 2026, Jeju Air canceled 6 July and had no operations on 7 and 8 July, and Star Marianas Air suspended flights from Saturday through Tuesday. Guam airport advisories note that rebooking depends on the airline, the route and seat availability, and that limited frequencies can extend the wait further.
