This airline is terrible. Book any other airline than this one. I was charged 12,500 Baht or $401.00 USD for 35kg of over weight baggage. The Thai people at the counter just made up this price. I contacted Thai Air and they agreed that this was to much! But I paid only because I was late for my flight. They took 20 minutes to charge me 12,250, and the gate was there furthest from the counter. And when I say the furthest, I mean it was at least a 15 minute RUN.
The agent was rude and deliberately made me late, then had the nerve to say, please hurry you'll be late, which was her doing. Pick any other Thai airline but this one. Let this airline go out of business. They would never have charged a Thai this amount, because no Thai would pay 12,250 baht for 35kg
