Bangkok's Don Muang Airport has suspended all flights after floodwaters breached its northern perimeter.
The airport, mainly used for domestic and low-cost flights, is in located in northern Bangkok, the area of the city worst hit by floods.
Bangkok's main international hub, Suvarnabhumi Airport, is in south-west of city and still operational after its flood defenses were reinforced recently.
Part of Don Muang is still being used as an evacuation centre for Bangkok residents after closing to the travelling public at 7pm local time. The airport is also serving as the government's flood crisis management centre as they battle to get the crisis under control. Relief officials said they had no plans to relocate.
The airport operator said the closure was for the sake of safety as flood runoff from the north flowed onto the runways and affected lighting, according to the Bangkok Post.
Don Muang has been threatened by encroaching water for days and runways are not expected to reopen for a week.
Seven districts of Bangkok are now at risk of flooding after Bang Phlad - home to department stores, universities and hospitals - was added to the list by Bangkok Governor Sukhumbhand Paribatra on Monday.
Central areas of Bangkok remain dry, but the Chao Phraya reached record high on Monday.
Thai authorities have declared a holiday in several provinces, including Bangkok, to help people cope with the flooding.
