As of today (October 25), Bangkok's domestic airport, Don Muang, has been closed. As for Bangkok International Airport (Suvarnabhumi), it is currently open; however, residents and visitors alike should check frequently to determine whether it is open or closed, as the situation in Bangkok is very fluid.
With flood-waters advancing on the capital, Prime Minister Yingluck Shinawatra has been forced to declare a five-day public holiday in preparation for the onslaught. The cabinet ordered the holiday to span October 27-31 for Bangkok and 20 other provinces affected by the Kingdom's worst flooding in 50 years. Shinawatra emphasized in her statement that all of Bangkok, including the inner zone, would flood, with water levels approaching 1.5 meters in some areas.
COMMENT: Don Muang, Bangkok's domestic airport, is primarily being used as an evacuation assembly point and a headquarters for flood relief assistance. Normally, both airports service roughly 100 flights per day (each).
The public holidays are designed to allow Bangkok's 12 million residents to brace for the floods now creeping towards the city center after swamping other parts of the nation, killing some 360 people and damaging millions of homes. The Chao Phraya River reached record highs of of 2.30 meters on Monday (October 24) with the possibility of water reaching 2.60 meters. Flood embankments can only hold back 2.50 meters of water.
