Which airline do you prefer or recommand ?
I had good expirience with Emirates and Thai-Airways for long oversea flights.
For short domestic flights in Asia I always choose the cheap ones like Air Asia or Nok-Air.

If you want to see a cockpit door opened with an axe by the pilots, you should probably book for Lao Airlines.
