The current immigration problems at Bangkok’s Suvarnabhumi Airport do not seem like they will be going away anytime soon. Passengers have become disgusted over incredibly long waits of 3-4 hours at peak times to clear immigration control at the almost six-year old airport and it looks like they will be for the foreseeable future.
Immigration officials have pointed to a number of different reasons for the delays but one of the most intractable may be the physical size of the airport and the number of people that are now trying to use it on a daily basis. Originally built to accommodate 80,000 people per day, the airport is now handling 16-180,000 arrivals and departures per day with an increase of another 14,000 per day expected over the next five years.
Compounding the problem is the current shortage of capable immigration officials. There are now only 1,045 officers, about 20% below the ideal complement of personnel. This situation is being addressed as well as possible but the physical limitations must also be addressed if the wait times are to be shortened, according to immigration officials.
So for the foreseeable future be prepared to get to Suvarnabhumi 3-4 hours before any international flight you may be taking or risk missing your flight.
