Bangkok flooding disrupts operations at Suvarnabhumi and Don Mueang airports

Disruption overview

Flooding in Bangkok continued to disrupt airport operations on 28 September 2026, even though Suvarnabhumi Airport (BKK) and Don Mueang International Airport (DMK) remained open and scheduled flights kept running. After almost 300 mm of rain fell in 48 hours from 24 September 2026, flooded access roads stopped ground-handling staff from reaching Suvarnabhumi, leaving Thai Airways short of check-in and baggage staff and disrupting in-flight catering. AirAsia, Nok Air, Thai Lion Air, and Thai Vietjet are also offering flexible rebooking or travel credits for tickets dated 26–28 September 2026. Because the disruption is linked to severe weather, compensation is unlikely, but airlines should still provide care and assistance if your journey is delayed.

Disruption details

Flooding in Bangkok continued to disrupt airport operations on 28 September 2026, even though Suvarnabhumi Airport (BKK) and Don Mueang International Airport (DMK) remained open and scheduled flights were still operating. For passengers, that meant difficult journeys to the airport, longer waits, and extra uncertainty even when their flight was still on the board.

Record-breaking rain that began on 24 September 2026 dumped almost 300 mm of water on the Thai capital in 48 hours. The Bangkok Metropolitan Administration declared all 50 districts flood-disaster zones on 26 September 2026, and while the heaviest rain has now eased, standing water is still slowing travel across low-lying parts of the city.

The pressure has been most visible at Suvarnabhumi Airport. Flooded access roads stopped ground-handling staff from reaching the airport on 26 and 27 September 2026, leaving Thai Airways short of people at check-in counters and baggage halls just as travelers were trying to navigate flooded streets and patchy transport links.

The disruption didn't stop at check-in. Catering trucks were unable to reach the apron, so several flights departed without the usual hot-meal service. Water-damaged luggage carts added another operational problem, pushing airport teams to repair equipment quickly and put special baggage-tracking measures in place while they worked through the backlog.

Airports of Thailand and Thai Airways have been deploying emergency reserve staff to help stabilize operations. Even with those measures, staff shortages and supply-chain problems can still create knock-on delays after the rain itself has eased.

Bangkok's other main airport, Don Mueang International Airport, has also stayed open. AirAsia, Nok Air, Thai Lion Air, and Thai Vietjet have all introduced flexible rebooking or travel-credit options for tickets dated 26–28 September 2026, recognizing that some passengers may be unable to reach the airport at all, even if their flight is running.

The wider city disruption explains why the situation is taking time to settle. Flooding has badly affected surface transport across Bangkok, while hotels, retailers, and food businesses have been operating with skeleton staff or shorter hours because employees can't commute. Schools are closed, the Bangkok Flower Festival canceled its final weekend on 26 and 27 September 2026, and Thailand's prime minister declared 28 and 29 September 2026 temporary public holidays to reduce pressure on commuters.

Travel companies have been adapting day by day. Destination management teams are checking on clients and rearranging transfers where roads are still impassable, while the Association of Thai Travel Agents is working with the Ministry of Tourism on emergency financial support for tour groups stranded by flooded highways or landslide-prone routes. Hotels are also being urged to keep guests updated in real time about transfer options because clear runways don't always mean clear roads.

Meteorologists expect the low-pressure system to move east later on 28 September 2026 toward Kanchanaburi and Chanthaburi provinces. But with water still lingering in parts of Bangkok, airport access and staffing could remain uneven for a little longer.

If your flight to or from Bangkok is disrupted because of this weather, compensation under EC 261 or similar rules is unlikely because severe weather is outside the airline's control. That doesn't mean you're without support. Your airline should still help with rebooking or refunds, and provide care such as food, refreshments, and accommodation if your delay is long enough.
