On 26 September, AOT said Suvarnabhumi and Don Mueang are open, with no flight cancellations and normal apron operations. Flooding at Don Mueang was mainly at an Air Force base, and the commercial side is open, though some water is on Vibhavadi-Rangsit road outside. AOT has raised pumping at its retention ponds from 2 to up to 6 pumps and says spare capacity remains. On 25 September, heavy traffic left passengers stranded at Suvarnabhumi; AOT is working with Grab on driver incentives and airlines are allowing free rebooking for flood-affected travellers. If you ship goods or send staff through these airports, allow extra travel time and check your flight status before leaving.
