On March 25th Don Muang airport will reopen to regularly schedule domestic traffic.
Currently the old Bangkok Thailand airport is being used for charter flights only.
Don Muang airport new code will be DMK, as the old code was assigned to Suvarnabhumi when it opened.
There is talk also of resuming some regional international flights in to Don Muang as well, the popularity of low cost regional international flights with carriers like Air Asia and Jet Star which offer cheap flights to Singapore, Cambodia, Viet Nam and even to China and Australia being extremely popular due to their cutting the cost by over half for many of the cities that they serve, these flights are extremely popular with businessmen seeking discount budget flights, as well as tourists to South East Asia.
The new Bangkok airport is reportedly already maxing out at 45 million passengers a year projected.
The main reasons given to reopen Bangkok's old airport to regularly scheduled flights was to lighten the load so that they could examine and repair construction faults at Bangkok's new international airport Suvarnabhumi, which has the airport designation code of BKK.
There have been lots of allegations of corruption during the construction at the new airport, one of the reasons given to support the coup last year in September.
They are looking to repair alleged construction faults on the runways, taxiways and other problems.
As a tourist flying in there should be no real problems unless you need to catch a connecting flight out of the other airport.
Traffic in Bangkok can be measured in meters rather than Kilometers per hours on a cross town trip during peak periods.
If you started out on a Friday Afternoon you would most likely end sometime on Friday evening, sure to test anyone's patience.
Maybe a good service for the Thais to consider would be a helicopter or air shuttle to the other airport.
I would sense that for some the added cost to the trip would be worth it to insure that they made their connections.
