Over 176,000 kilometers of national highways and rural roads link tiny hamlets with provincial capitals and major cities. The State Railway operates an efficient rail system linking Bangkok with northern, northeast and central Thailand while a southern route allows direct rail travel from Bangkok to Malaysia and Singapore. Despite the rapid growth of inter-provincial buses, train travel is still popular with a large segment of the population.

Thailand has 23 airports and six international airports, namely Don Muang, Phuket, Hat Yai, Chiang Mai, Chiang Rai, and U-Tapao. All except U-Tapao are operated by the Airports Authority of Thailand.

Since its founding in 1960, Thai Airways International, Thailand's national carrier, has enjoyed remarkable success. It operates regular wide-bodied jet services to more than 50 major cities in Europe, North America, the Middle East, Asia, and Australasia.

In addition, Thai Airways provides an excellent domestic service, as well as feeder routes and to airports too small to accommodate jets. Thailand also has two private airlines - Bangkok Airways and Angel Airlines - which ply some of the domestic routes.
