A major labor union said the rise in unruly airline passengers is 'deeply concerning' — after 2 fights days apart on the same Ryanair route

• Two Ryanair flights on the same route were disrupted by fighting passengers six days apart.
• A major UK union has now raised its concerns with airports and airlines, per the BBC.

A labor union has raised its concerns with airports and airlines about the rise in unruly passengers, the BBC reported.

Pat McIlvogue, an industrial officer with Unite — one of the UK's two largest unions with 1.4 million members — told the BBC it has reached out to airlines and airports across Scotland after two incidents in a week.

"The proliferation in incidents of anti-social behavior and threats towards workers at airports and on flights is deeply concerning," he said.

"It's totally unacceptable that any worker has to confront threats of verbal or physical abuse, and the situation needs to be urgently addressed."

The two incidents both took place on flights with the ultra-low-cost carrier Ryanair from Edinburgh to Tenerife — a Spanish island popular with British tourists.

On February 19, two men and a woman were filmed throwing punches and even a headbutt while threatening other passengers who tried to calm them down.

The trio were removed from the plane by local police when it touched down in Tenerife, a Ryanair spokesperson told the Daily Record.

"The crew were unable to control them and the pilot stayed in his cockpit until the end," the woman who filmed the video told the newspaper.

Six days later, another flight on the same route was diverted to Portugal after a midair brawl in which passengers threw bottles, the Daily Record reported.

"The airline should be given more support to take enforcement action when they see the crowd getting rowdy," a witness told the newspaper. "The stewards tried to calm it down but they were powerless."

Ryanair did not immediately respond to a request for comment from Business Insider.

Last month, the US Department of Transportation shared a reminder online that unruly passengers can be fined up to $37,000 — after two people were filmed fighting on as Southwest flight.
