Thailand has a wide range of transport options that make it very easy to travel through the country affordably and relatively quickly. Thailand has few domestic full-service and low-cost airlines serving a large network of domestic airports.
THAI Airways and Bangkok Airways are the major full-service airlines on the internal flight network. Low-cost carriers such as Thai AirAsia, Thai Smile, Thai Lionair and Nok Air make traveling by air inside Thailand convenient for a very reasonable price.
Fares with the low-cost carriers are often comparable to train or bus fares, especially if you book online far enough in advance. Airline tickets can be purchased online direct with the airlines or through travel agents and third-party flight agencies.
There are plenty of domestic airports to choose from.
