Fight or flight.

Video showing a shirtless man punching a fellow plane passenger has gone viral on Twitter, with users stunned by the brazen act of violence.

The footage — initially posted to Twitter late last month — was recorded on board a Boeing 777 operated by Biman Bangladesh Airlines, the national flag carrier of Bangladesh.

The shocking clip shows the shirtless man standing over another passenger, who is seated in an exit row.

The two begin to tussle before the topless traveler starts throwing punches, striking the seated man in the head. He was eventually restrained by other passengers, but it is unclear if he was arrested.

The altercation was said to be over a seat allocation, Jam Press reported.

Airline travel appears to have become more unruly as travelers return to the skies in the wake of the COVID-19 pandemic.
