Nitinai Sirismatthakarn, president of AoT said from Jan. 30 to Feb. 11 total air passengers at AoT's six airports - Suvarnabhumi, Don Mueang, Phuket, Chiang Rai, Hat Yai and Chiang Mai - are expected to increase by 4 percent.

The number of flights is predicted to rise by 7.2 percent compared with the same period last year, with 800 charter flights and extra flights catering to some 119,000 passengers.

AoT forecasts Bangkok's Suvarnabhumi airport to be the most jam-packed, with 2.63 million passengers, or growth of 3.6 percent year-on-year, from 14,800 flights, a 9 percent increase. Some 40,000 passengers will travel via 300 charter and extra flights.

Aeronautical Radio director Somnuk Rongthong said air traffic controllers have been put on full alert to monitor the airspace and clear up any delays during the holiday, which lasts from Feb. 4-10.

The Tourism Authority of Thailand expects to welcome over 330,000 Chinese tourists during the seven-day period (Feb. 4-10). They represent more than 30 percent of the overall total of 1.03 million international arrivals that are expected to visit Thailand over the Chinese New Year.
