Tokyo Haneda Dujuan Waiver Deadline Is September 24

Delta Air Lines posted a weather waiver for Tropical Storm Dujuan that covers travel to, from, or through Tokyo Haneda Airport on September 20 and September 21, 2026. The carrier says customers can change those flights at no extra cost if they stay in the same cabin and complete the change by September 24, 2026, on tickets issued on or before September 18.

That is a booking decision, not a cancellation bulletin. If your itinerary touches Haneda on those two dates, use Delta and other airline planning pages to confirm the ticket date, then change or take an eCredit before the September 24 cutoff rather than waiting for a gate-agent surprise.

Delta’s Haneda Waiver Covers Sept. 20 and 21

The Delta tropical storm advisory names one city pair group: Tokyo Haneda. It does not list Narita, Osaka, Nagoya, or a nationwide Japan waiver. Travelers connecting over Haneda on the 20th or 21st sit inside the same window even if Tokyo is not the trip’s origin or destination.

Delta has not said it is canceling Haneda flights. The notice says travel “may be affected” and then sets the free-change rules. Treat it as permission to move, not as proof that your flight already failed. Check the app or My Trips for the actual aircraft status on the day you fly.

The waiver applies only to tickets issued on or before September 18, 2026. A ticket bought on September 19 or later does not inherit this storm window, even if the flight still operates on the 20th or 21st. Keep the original issue date from the receipt before you call or click change.

Ticket Changes Must Stay in the Same Cabin

To keep the fare difference waived, rebooked travel has to occur on or before September 24, 2026, in the same cabin as the original ticket. If the original booking class is gone, Delta says a fare difference may still apply. Changing origin or destination can also trigger a collection at booking.

Customers who cannot use the new dates may cancel and take an eCredit for future travel, with unused ticket value good within one year of the original issue date. That path is useful when Silver Week plans collapse and a later Japan trip is more realistic than a 24 September departure. Any fare difference on a new ticket is still collected.

Do the change in the Delta app or on delta.com under My Trips. The advisory tells customers to update the flight within the rebooking window to have fare differences waived. A change after September 24, or a new departure after that date, leaves the ordinary fare difference in place.

Typhoon Dujuan Is Aimed at Kanto Over Silver Week

The Japan Times, citing the Japan Meteorological Agency on Friday, said Dujuan would pass the Ogasawara Islands, then the Izu Islands on Sunday, and could approach the Pacific coast of eastern Japan from Sunday into Monday. That Monday window is September 21, the second of Delta’s two waiver dates, during Silver Week holiday travel.

Friday’s JMA figures, as reported there, put the storm about 170 kilometers south-southeast of Chichijima at 3 p.m., moving west-northwest at 35 kph, with a 975 hectopascal center and sustained winds near 108 kph. The agency warned of up to 250 millimeters of rain on the Ogasawara Islands in 24 hours, 200 millimeters on the Izu Islands, and 150 millimeters in parts of Kanto, with another 200 millimeters possible in Kanto through noon Monday.

Winds around the Izu Islands were forecast to reach 101 kph on Sunday, with gusts as high as 144 kph, and waves of as much as 6 meters along the Kanto coast. The agency also flagged landslide, flooding, and swollen-river risk, plus heavy rain along the Pacific coast from Tokai through northeastern Japan. Dujuan was forecast to accelerate northeast and move away over the Pacific by Tuesday.

Those Friday numbers will age. Use them as the reason Delta opened a two-day Haneda window, then refresh the live JMA bulletin before you lock a new departure. A storm that turns earlier or later does not automatically rewrite Delta’s September 24 paperwork.

Narita Tickets and Other Airlines Sit Outside This Notice

Tokyo has two international airports. This Delta page is Haneda only. A Narita arrival, a Haneda-to-Narita ground transfer, or a codeshare marketed by another airline is not covered just because the city name is Tokyo. Read the ticket’s operating carrier and the airport code before you assume a free change.

Other U.S. and Japanese carriers may post their own Dujuan waivers, or they may not. Do not copy Delta’s dates onto a United, American, Japan Airlines, or ANA ticket. If a partner operates the metal and Delta markets the seat, confirm which ticket stock you hold before you click.

Ground plans in Tokyo are a separate decision. Silver Week visitors headed to Tokyo Disney Resort still need a way into the city on Monday if Haneda slows. Park hours do not change because Delta opened a waiver. Build slack between a late inbound and a first park reservation rather than stacking them on the same morning.

Domestic Japan transport is already taking weather hits on a different booking. Deep Arrival’s note on Taiheiyo Ferry Nagoya cancellations through September 21 is the ferry half of the same storm week, not a substitute for a Haneda air ticket.

Tokyo Holiday Plans Still Depend on Monday’s Weather

Silver Week packs the calendar around Respect for the Aged Day and the autumn equinox, which is why a Monday Kanto approach is operationally louder than a midweek storm. Hotel check-in windows, rail seat reservations, and first-day park tickets are harder to slide than a single transpacific segment. If you move the Delta flight, move the hotel night with it or you will pay for an empty room in Tokyo and a night in a U.S. connecting city.

Inbound guests who keep the original Haneda time should pack for wind and rain on the 21st and leave extra time for the monorail or Keikyu ride into the city. Outbound guests leaving Haneda on the 20th or 21st should treat the waiver as a chance to leave a day earlier, not as a reason to arrive at Terminal 3 at the last minute. Delta has not promised that every bank will fly as scheduled.

If the storm’s closest approach slips past Monday night, the waiver still ends on September 24 unless Delta publishes a new advisory. Do not wait for a second email. Screenshot the current notice, change while inventory remains in your cabin, and keep the confirmation number with the original issue date.
