A Chinese family was kicked off a Cathay Pacific flight en route to Hong Kong last Thursday after a three-year-boy refused to wear his seatbelt during take-off.

The aircraft reportedly was delayed at Bangkok’s Suvarnabhumi International Airport for about 30 minutes as the cabin erupted in shouts from family, flight attendants and other passengers angered over the incident, according to the Daily Mail.

After boarding, flight attendants reportedly asked the family that the boy sit in his own seat and fasten his seatbelt.  Airline regulations allow children two and under to sit on a parent’s lap during take-off.  But the unidentified boy had surpassed Cathay Pacific’s age restriction and parents insisting that the boy remain seated in his mother’s lap, reports the South China Morning Post.

A heated argument ensued, with other passengers getting involved. A passenger on the Cathay Pacific flight recorded a video as the family was being escorted from the aircraft.

In the clip, the alleged father of the boy says “If others keep on harassing us, then we will not leave.”

A passenger is heard in the background urging the airline crew to call police.

“We are customers too. Why are you two allowed to harass all the passengers on board?” she says, according to a translation from the Daily Mail.

The incident was reportedly resolved when the family decided to deplane the aircraft, with the mother reportedly carrying the crying boy.
