A number of travellers asked to switch seats to get away from the girls, who were said to be aged between 20 and 25.
One passenger, Amber Elouise Ferguson, witnessed the behaviour and uploaded pictures of the girls to Facebook. She wrote: "Anyone know these girls?? Just delayed our plane to Ibiza, they've been racist, making rude comments & threatening people!"
Speaking to the Manchester Evening News, Amber said: "When my friends asked to move seats they started shouting abuse at them.
"We heard them say they would wait until the seat belt signs went off and then start fighting with all the passengers who had asked them to be quiet.
"They told me 'you don't know who you are dealing with and you'll get dealt with'."
According to the Metro, she added: "I think their behaviour was disgusting, everyone on the way to Ibiza gets merry and loud but it's usually just fun banter.
"It's unacceptable, childish, uneducated behaviour. The girls should be utterly ashamed and disgusted with themselves.It could have ended up being a very dangerous flight."
The Telegraph reports that a spokesman for Monarch confirmed that four passengers were removed from the flight and added: "Monarch takes a zero tolerance approach to disruptive behaviour on board all of our flights.
"The safety and security of our passengers, crew and aircraft is our absolute priority."
