Air travel in Thailand has become very cost effective over the last number of years. Deregulation has allowed a number of low-cost and independent airlines to emerge catering for both domestic and international routes. As a result Thailand has a wide variety of low-cost and independent airlines providing flights to many locations within the kingdom. Special offer ‘ticketless’ flights ordered over the Internet can cost as little as 99 Baht one way to places like Khon Kaen with average one-way costs to most locations around the 1,000-2,000 Baht mark.
