Airline bosses have warned travellers about their behaviour after 'rowdy' passengers allegedly forced a plane to turn back to Liverpool airport.
Police escorted several disruptive passengers off the easyJet flight from John Lennon Airport to Amsterdam on Friday night.
Other passengers were then forced to stay at a hotel after the flight was aborted.
EasyJet said it will not tolerate abusive or threatening behaviour.
Liverpool John Lennon Airport is celebrating its 80th birthday.
Originally known as Speke Airport, then RAF Speke, Liverpool Airport added the name of the city's most famous son in 2002.
Jim Keight, who was present when the airport opened, cut the birthday cake today.
