How to book your flight ticket online with Thai Airways?
Airlines like Thai Airways are good and reliable airlines to fly with and making an online booking yourself might be cheaper as via a agent. But .... be careful, most airlines have a habit of trying to sell you a bit more as only the cheap ticket.
So at 6 June 2015 I made a test booking online with Thai Airways and noted what they are trying to sell you while you are booking your cheap flight. Mind you, that can change in the future.
So Thai Airways : Expensive and not much better as Thai Smile or Nok Air. First of all be aware that at the web-site of Thai Airways also the flights of Thai Smile are sold, but it is cheaper to book them via the web-site of Thai Smile.
