Passengers who were booked on an easyJet flight from Nice, France to Luton, outside London, endured a 13-hour delay for mechanical issues, while other easyJet flights to Luton were taking off on schedule. A passenger carrying a baby approached a customer service agent for a company called Samsic, a private company that contracts passenger assistance services. It’s unclear what happened next. The man waved a cellphone, the agent knocked it away, the man pushed the agent, the agent punched the man in the face. Eventually, the plane left for Luton, with the man and his baby on board. easyJet, who were quick to point out that the Samsic agent was not on their payroll, is investigating.
