The airline said despite repeated warnings from the crew, the party continued to behave in an “appalling and aggressive” manner, leaving it no choice but to divert to Toulouse.
Police and airport officials were on standby to escort the revellers off the aircraft.
Jet2.com said the crew decided to suspend sales of alcohol on the flight after one member of the group was refused boarding for being “drunk and aggressive”.
Despite this, the airline said the rest of the party continued to act in a “deplorable and aggressive” fashion once airborne, despite there being families with young children present.
Following the incident on Friday (June 22), Jet2.com has renewed its call for action to better control the sale, and consumption, of alcohol and tax-free goods at airports.
In a statement, Jet2.com said the cumulative effect of alcohol consumption at the airport, and while onboard, contributed to the drunken behaviour.
Phil Ward, Jet2.com managing director, said: “A large number of individuals from this group have left a stag weekend in ruins, and have subjected our crew and customers to a continued pattern of disgraceful and aggressive behaviour.
“This left some of our highly-trained cabin crew extremely upset, and the captain had no choice but to divert the aircraft so police could offload the group.
“Fellow customers and families travelling for a well-earned holiday should not be subjected to this behaviour and we will now be taking further action in support of our crew to ensure those responsible are held accountable for their actions.
“This is the second time that disruptive passenger behaviour has caused one of our flights to be diverted in just a few weeks, so enough is enough.
“Proper measures need putting in place by the industry and government to ensure that our crew and customers can fly in a safe, trouble-free environment.
“As a family friendly airline flying millions of people on holiday every year, we are demanding that proper action is taken to protect our crew and customers from this appalling behaviour.”
