Glasgow Airport staff dealt with 125 incidents of drunken disruption last year, management said.

The figure was announced as the airport stepped up its campaign of zero tolerance towards passengers who cause disruption before flying.

Management said the key aim of the Campus Watch scheme is early intervention, with staff encouraged to report the details of any potential incident to the airport's central control room.

Check-in staff, security teams, bar and restaurant employees, retailers and airline crews are all taking part in the initiative.

Managing director Amanda McMillan said: "For many of our passengers, their holiday begins the moment they arrive at the airport and we want them to continue to enjoy a memorable but ultimately safe and disruption-free experience.

"In 2016, we carried a record 9.4 million passengers and during this time our staff and partners dealt with 125 incidents of disruptive behaviour involving alcohol.

"While it's correct to show the numbers in context, it's also important to understand that disruptive behaviour can often disproportionately affect a large number of passengers, particularly if an incident occurs on board an aircraft."

Other steps taken under the Campus Watch initiative include airlines making authorities aware of large group bookings and police patrols at the drop-off area ahead of potentially problematic flights.

Inspector Bob Smith, the airport police commander, said: "Glasgow Airport has a zero-tolerance approach to unacceptable or disruptive behaviour.

"Thankfully, incidents of this type are rare but when they do occur, they can delay flights, affect local businesses in the airport and ultimately cause misery to other passengers.

"It's completely understandable that people want to start their holiday with a bit of fun but passengers should drink responsibly and be fit to fly."
