The operators of Belfast International Airport have reminded passengers that they will be refused access to their flights if their behaviour is unacceptable, after an upsurge in such incidents.
A spokeswoman for the airport said that in recent weeks there have been a number of cases where groups and individuals were turned back at departure gates, or off-loaded from aircraft.
Such incidents are often linked to drink.
Although she could not provide an estimate for the number of passengers involved, and said such incidents happen every year, she said such behaviour seemed to have been occurring more often recently.
In a statement, Rod Haskins, the airport operations and security manager, said: “We want all of our passengers to have a good experience when they travel through our airport.
“We’re not trying to stop customers from having a good time but there have been occasions when boisterous behaviour, often alcohol related, has caused problems.
“This leads to obvious disappointment for the individuals and their companions.”
