The decision was made by the airport company's board of directors, and will have to be approved by the Cabinet, as 70 per cent of the company's shares are still owned by the government.
The company has revealed that airlines in the One World group, led by Hong Kong-based Cathay Pacific airway, has expressed interest in using Don Muang airport. The airlines group also suggested that Don Muang airport be expanded to allow for giant Airbus A380 aircrafts to land and take off from there.
Don Muang airport is currently operating as an airport for budget airlines. The decision will turn it into a full-service airport.
Bangkok's main international airport, Suvarnabhumi, has the capacity of 45 million passengers per year. Now it is handling over 51 million passengers per year. The Airport of Thailand expects Don Muang airport to ease the crowding problem at Suvarnabhumi while the country's number one airport is being expanded to allow it to handle 60 million passengers by 2017.
