This is the astonishing moment an overweight tourist was dragged out of a plane for allegedly demanding an emergency aisle seat for his bigger frame.

The entitled passenger reportedly complained there was not enough room in his window seat on the Thai Lion Air flight leaving from Bangkok on June 25.

He requested to be transferred to the emergency exit seat, which had more leg room, but allegedly threw a tantrum when flight attendants refused to grant his request.

The man's fit was said to have delayed the flight by around an hour before police arrived to drag him off the Boeing 737 aircraft.

Footage shows officers yanking the stubborn passenger, seen in the video wearing an orange Garfield shirt, off his seat. He then lay down and blocked the aisle in protest.

Furious passengers screamed at him to 'get out of the way' as airport police hauled his bulky body off the jet. Another female passenger was heard branding the man 'selfish'.

'When you said apologise for the first thing I said, don't forget that,' another woman yelled at him.

Police carried the man by his arms and legs to eventually remove him from the aircraft. It took off around an hour later from the Don Mueang International Airport (DMK).

The filmer said: 'At first, I thought we couldn't take off because the man had fallen ill. It turned out he just thought the economy seat was too crowded and insisted on moving to the emergency exit.

'The flight attendants had to call the police because he refused to cooperate.'
