A fight broke out between a Chinese woman and a Thai woman after the former tried to cut into a queue in front of a check-in counter at Don Mueang airport.
The incident was filmed and posted on Chaiwat Tanawatpornchai's Facebook page on Friday morning.
According to the poster, the two passengers started shouting at each other. As they started to get physical, several men intervened to break up the brawl.
The poster said the fight erupted after the Chinese woman attempted to cut to the front of the line at the baggage check-in counter of the no-frills carrier Thai Lion Air.
On the Thai webboard Pantip.com, users wrote that quarrels involving Chinese people were frequent in Thailand this year. Others wrote that Thai people should keep their cool, particularly with tourists.
Thai Lion Air has yet to comment on the issue.
