Thai Airways is Thailand's flag ship carrier. It's partly government owned and it`s main office located in Bangkok. Thai airways is also the country's international airline so it has quite an extensive support infrastructure in place. The airline is considered a four star airline, and even on short hop flights, passengers get snacks and some type of in-flight entertainment. A big benefit of flying Thai is that the airline is a member of Star Alliance group .

Bangkok Airways calls itself "Asia's boutique airline," and though that phrase tends to confuse people, what it means is that Bangkok Airways is a small airline with limited flights but offering flights to many destintaions within Thailand and the neighbouring countries. One advantage about flying Bangkok Airways is the fact that they have their own lounges in many of Thailand's airports. Passengers can enjoy snacks and drinks and peace and quiet before boarding their flights.

Air Asia offers flights from Bangkok to 11 different domestic destinations, including Phuket, Chiang Mai and Krabi. In 2010, Air Asia was ranked the world's best budget carrier by Skytrax thanks to the airlines cheap prices, great service and comprehensive routes. Though flying Air Asia is definitely a pleasant experience,but pls don`t forget the fact that it's still a budget airline, so you'll pay extra if you want to check bags, pick your seat, or have a meal. The airline allows you to reschedule flights before departure for a fee.

The budget airline, a joint venture with Thai Airways, has embraced a bird theme ("nok" means bird in Thai) and so all of the airplanes are painted like colorful birds, flight attendants wear yellow bird outfits. Aside from the cuteness factor, Nok has multiple daily flights from Bangkok to the country's most popular tourist destinations. Maybe it's just Thai hospitality, but staff and crew always seem to be super nice on Nok Air. And although it's a budget carrier, you can pick most seats for free. Nok Air also allows customers to pay for flights in an innovative way: Passengers can book their flight on the phone and then pay for it at a local ATM (with the reservation code the agent will give you).

Orient Thai is a budget carrier, which also operates under the name One Two Go. Orient Thai has daily flights from Bangkok to Phuket, Chiang Mai, Hat Yai and a handful of other destinations in Thailand. Many of the flights operated in Bangkok's old airport, Don Muang, NOT IN THE new international airport. Orient Thai is a budget airline but offers passengers a few free extras, including free snacks, free seat selection and 20 kilos of checked baggage.
