Taxiway C4 at Suvarnabhumi Airport, Bangkok, with maintenance vehicles on the airfield

A soft patch of runway at Bangkok's Suvarnabhumi Airport trapped a departing jet on the evening of 28 October 2026 and delayed five flights. The damaged section was repaired and reopened, but Airports of Thailand (AOT) now plans rolling night-time repairs at risk spots across the airfield, and the Civil Aviation Authority of Thailand (CAAT) has ordered a full check of runways, taxiways and aprons. Here is what happened, what the repairs mean for passengers, and a few other things to know if you are flying in or out of Bangkok in early November.

Last reviewed 2 November 2026. Checked against reports from Thai PBS World, the Bangkok Post, The Nation, MGR Online and Transport Journal quoting the Ministry of Transport, AOT and CAAT, plus warnings from the Office of the National Water Resources (ONWR) and the Department of Disaster Prevention and Mitigation (DDPM).

At a glance

  • What happened: at about 7.20pm on Wednesday 28 October, China Airlines flight CI840 (a Boeing 737-800 to Kaohsiung, Taiwan) got its wheels stuck in a damaged, soft section of runway 02R near taxiway E21 while lining up for take-off.
  • Impact: four aircraft behind it were blocked and had to be pushed back one by one to use runway 02L instead. In total, five flights were delayed by about two hours.
  • Fixed: temporary repairs were completed and the section was due to reopen at about 6pm on 29 October after surface-density checks. The airport said it had verified the surface was fit for use and that overall airport services were not affected.
  • Cause (so far): AOT says the airport sits on soft soil with a high water content, and recent flooding and heavy rain pushed water up close to the runway's surface layers. CAAT says worn construction materials may also be a factor. Investigations continue.
  • What's next: AOT will scan the airfield and repair risk spots section by section, typically closing an area from 8pm to 6am for about ten days before moving to the next. The whole runway will not be closed.

What happened on 28 October

According to the Ministry of Transport report quoted by The Nation, CI840 used taxiway E21 to line up on runway 02R when its wheels sank into soft surfacing. It could not move forward. The four aircraft queuing behind it were Thai Vietjet TVJ2308 to Phuket, Thai Airways THA349 to Islamabad, China Southern CSN364 to Guangzhou and Thai Airways THA317 to Mumbai. Tugs pushed them back so they could reach runway 02L.

The Bangkok Post reported that it took ground crews about five hours to move the China Airlines aircraft. The airline arranged alternative flights for all 116 passengers and eight crew, along with hotel rooms, food and drinks while they waited. Aeronautical Radio of Thailand (AEROTHAI) worked with AOT to manage traffic on the other runways.

Why the runway gave way

Suvarnabhumi opened in September 2006 on low-lying land that was once a natural floodway, known locally as Nong Ngu Hao, or "Cobra Swamp", the Bangkok Post notes.

AOT president Paweena Jariyathitipong said on 30 October that the airport has handled around 700,000 flights a year for 20 years. Engineering checks found the soil layers are soft and hold a lot of water. After the recent floods and heavy rain, groundwater rose close to the asphalt layer, which can flex and shift. MGR Online reported that the spot that failed had been patched temporarily while waiting for permanent repair. That is normally fine, but the extra water reduced its strength.

AOT says the areas that most need watching are where aircraft turn: taxiway exits, turning points and runway ends. It says it has done major runway repairs going deeper than the surface layer three times in the past ten years.

What CAAT has ordered

CAAT director Air Chief Marshal Manat Chavanaprayoon has written to AOT asking for an explanation and a report on measures to prevent a repeat. CAAT has told AOT to inspect runways, taxiways and aircraft parking aprons in full, especially risk spots. It recommended non-destructive inspection (NDI) equipment, which can check the strength of the surface and the structure below without drilling. He said the same safety standard must apply whether or not it is tourist season.

What it means if you are flying this month

For most passengers, the practical impact should be small. Repairs will be done section by section overnight, and AOT says it will not close a whole runway. Still:

  • Late-evening and overnight flights are the most likely to be affected by any work between 8pm and 6am. Runway use may be adjusted while work is under way.
  • Check your flight status on the day with your airline. If a flight is delayed or rerouted, the airline, not the airport, handles rebooking, meals and hotels.
  • Leave extra time. The DDPM and ONWR tidal flood warnings (below) list roads including Sukhumvit, Suksawat and Rama II as possibly affected, so allow more time if your route to the airport uses them.

Security checks: hand searches and checked bags

At the same briefing, AOT apologised after a security screener at Suvarnabhumi behaved inappropriately towards a passenger on 28 October. Paweena said screening has moved from hand-held metal detectors to more hand (pat-down) searches, which some passengers find uncomfortable, and that staff have been told to give the best possible service.

She also defended the opening of some checked bags for inspection, calling it an international safety standard, and said the process is monitored on CCTV. We explained how those checks work and how to pack for them in our earlier guide on CAAT's checked-bag inspections.

Arrival queues

The National Tourism Policy Committee, meeting on 31 October, also discussed improvements to arrival clearance at Suvarnabhumi to cut queues and simplify entry for tourists, according to deputy government spokesperson Lalida Periswiwatana. No specific measures or dates were announced. If you are arriving at a busy time and want a quicker start, some travellers book an airport fast-track service; it is also worth arranging a Thailand eSIM before you land so you can check messages and call a ride as soon as you are off the plane.

Tidal flood alert in Bangkok until 4–5 November

This is separate from the runway issue, but useful for anyone in Bangkok this week:

  • The DDPM warned of high tides on the Chao Phraya from 27 October to 5 November, especially between 6am and 3pm. Riverside areas, communities outside flood walls and places without permanent flood defences are at risk in Bangkok, Pathum Thani, Nonthaburi, Nakhon Pathom, Samut Sakhon, Samut Songkhram and Samut Prakan.
  • The ONWR warned that from 31 October to 4 November, easterly winds could push river levels 0.30–0.50 metres above critical levels near the sea. It named Sukhumvit, Suksawat and Rama II roads as possibly affected, and added Chachoengsao to the list of provinces.

If you are staying by the river or using river piers, check conditions before you go and do not walk or ride through floodwater.

Checklist for flying via Suvarnabhumi in early November

  • Check your flight status with your airline on the day, especially for evening and overnight departures.
  • Allow extra road time, and more if your route uses Sukhumvit, Suksawat or Rama II during high tide.
  • Expect possible hand searches at security; keep liquids and electronics easy to reach.
  • Pack checked bags so they can be opened and closed easily; avoid locks that staff cannot open for inspection.
  • Keep your airline's contact details and booking reference handy in case of rebooking.
  • Have your arrival documents ready (passport, TDAC confirmation) to move faster through immigration.
