Nok Air CEO Patee Sarasin says his budget airline is halting operations until Nov. 1 at Don Muang airport, which is used for domestic flights within Thailand.

Patee says flights that have already departed other cities will be directed to Bangkok's Suvarnabhumi Airport, the country's main international gateway.

A spokesman at Don Muang confirmed water had entered a northern section of the airport. But he said runways were not affected and other flights are operating normally.
