Flight fight ... Four women have clashed midair in a flight to Hong Kong over a crying baby. Source: Supplied Source: Supplied

The Chongqing Morning News is reporting a brawl between four women aboard a flight between China and Hong Kong almost caused an in-flight emergency.

The ruckus, which happened only days after a woman flung boiling water at a flight attendant also on a flight to Hong Kong and a man opened an emergency exit for “fresh air”, saw four middle-aged women launch into each other.

Air China Flight CA433, which had departed Chongquin about 9am, had only just reached cruising altitude when two of the women grew angry at the sound of a crying baby behind them.

Snarky comments were exchanged, then the annoyed women reclined their seats as far back as possible to retaliate for the distressed baby’s cries.

Then fists started to fly.

Passengers told media the fight went on for “some time” before cabin crew managed to convince the brawling women that they would be even more inconvenienced if the aircraft had to turn back to the airport.

Police were waiting for the four when the China Air flight landed an hour later.
