邊位知去泰國曼谷機票哪間airline最平?

As your flight out to Bangkok is in Christmas peak, I think cheapest to fly with could be Orient Thai Airways... As all the other airlines would be rather expensive during Christmas peak...
However, you can go to travel agency as they may still have some relatively cheap tickets from other airlines other than Orient Thai... This is because travel agency usually hold a fair amount of tickets until last minute...
So if you contact some big travel agency, they may still have some cheaper tickets and package as they are still holding a number of tickets from various airlines... But never the less, its during the peak season, so there is the chance that those big travel agency will not have enough seats for their own group tour as well...

Try Orient Thai... In my experience, they are not too bad... Meal are just a little small in portion but still taste alright... And their aircraft looks a little old, but well maintained... So Orient Thai is pretty good...

Ethiopian Airlines should be the cheapest since it it only HKD$1633 excluding tax
