When the Ryanair flight from Edinburgh arrived at lunchtime last Thursday, police were waiting to arrest four passengers after airline staff called ahead to report the troublemakers.
During the brawl, a young child was reportedly hit on the head by a flying wine bottle.
It has now emerged that the scuffle broke out after members of a stag party taunted a fellow passenger because he was sporting a “man bun”, a style popular with hipsters.
Eyewitness Conor Cockburn who was travelling a few seats behind the stag party told The Sun that the constant taunts upset the girlfriend of the man with the “offending” hairstyle.
“The woman lost it and ‘jumped’ at the drunk revellers after they continuously shouted ‘topknot’ at her friend,” Cockburn said.
Passengers said the group celebrating the bachelor party had been “absolutely hammered” before they even got on the flight.
In a statement, Ryanair said: "The crew of this flight from Edinburgh to Alicante requested police assistance upon landing in Alicante, after four passengers became disruptive in-flight.
"The aircraft landed normally and the individuals were removed and detained by police in Alicante.
"We will not tolerate unruly or disruptive behaviour at any time and the safety and comfort of our customers, crew and aircraft is our number one priority. This is now a matter for local police."
