A Flybe flight was delayed for five hours after cabin crew called for assistance to deal with rowdy passengers.
The plane was due to take off from Newcastle Airport to Stansted on Sunday afternoon when the captain asked for help from the authorities.
Police boarded the aircraft and said four men who were part of a stag group were removed and spoken to.
A Northumbria Police spokesman said: "We were called by airport staff to help remove a group of drunk and disorderly passengers from a plane at Newcastle Airport.
"The group was escorted off the plane and spoken to."
Flybe said: "The safety of its passengers and crew is Flybe’s number one priority.
"As such, it operates a zero tolerance policy with any form of on-board behaviour that might in any way compromise the safe operation of any flight.
"The above flight was delayed due to the threatening and overly verbally abusive behaviour exhibited towards the cabin crew immediately prior to departure by members of a stag party.
"The captain elected to report the situation to the authorities who in turn called the police which took the necessary immediate action.
"All 68 passengers were offloaded and Flybe fulfilled its Duty of Care obligations under EU261 regulations. Those not involved in the incident were accommodated on an alternative flight that departed at 19:10, incurring a 4hr 45 minute delay for which Flybe once again apologises most sincerely to those passengers inconvenienced.
"In accordance with police recommendations, Flybe can confirm that none of the offending group was allowed to travel on the replacement flight."
