'Harry Potter' star slams Air Canada, saying the airline tore up his ticket and kicked him out of first class because the flight was full

• Matthew Lewis, aka Harry Potter's Neville Longbottom, revealed his bad experience flying with Air Canada.
• The actor said the airline moved him out of first class when he was at the gate and tore up his ticket.

"Harry Potter" actor Matthew Lewis has criticized airline Air Canada, saying he was kicked him out of first class just before he boarded a flight and had his ticket ripped up.

"Air Canada is the worst airline in North America. And that's saying something," Lewis, known for his role as Neville Longbottom in the "Harry Potter" film franchise, tweeted on Friday.

Lewis wrote in a following tweet that the airline moved him from first class to an economy seat when he was at the gate. He said staff tore his ticket up without giving him an explanation other than that the flight was full.

Lewis said in the tweet that staff advised him to go to customer service, but when he asked where it was, they said it was located in Toronto, Canada. He said he was in Orlando, Florida, at the time.

"Honestly never experienced anything like it. I've been bumped before. Comes with the territory. But at the gate, less than two minutes to boarding and without explanation or apology? Never." Lewis wrote in a separate tweet.

Air Canada responded to Lewis's tweet, saying it "regrets hearing" about his situation and told him to send the airline a message with details of the problem.

Air Canada didn't immediately respond to Insider's request for comment.

The airline said in a statement to CTV News Toronto on Friday that the situation was under review and declined to comment further.

Airlines sometimes oversell flight tickets in hopes that not all passengers will turn up for the journey. It means that companies can keep the extra revenue from selling more seats than a plane actually has.

One passenger told Insider last year that he was flying with Delta Air Lines from Minneapolis to Iceland when staff announced the flight was oversold by 30 people. Passengers had to bid for the ticket and he got $4,500 in credit to take the next flight.

Lewis is one of many thousands of passengers who have had to deal with travel disruption this summer.

Airlines have struggled to cope with the increase in travel demand while experiencing a staff shortage, leading to many flight cancellations, delays, and even reports of lost luggage and passengers being booked on the wrong flight.
