Passengers departing from UK airports this summer will encounter warnings about the cost of disruptive activity.

The ‘One Too Many’ campaign uses digital display screens in shops and bars to list the potential penalties, from being denied boarding to fines of up to £80,000 or even jail.

Participating airports are Manchester, Stansted, East Midlands, Aberdeen, Glasgow, Southampton, Heathrow, Belfast, Liverpool John Lennon, Leeds Bradford, Bristol, Birmingham, Newcastle and Gatwick.

The campaign also ran last summer.

Civil Aviation Authority figures showed the number of disruptive passenger incidents dropped slightly last year, from 417 to 413, though some regional leisure routes saw an increase.

Glasgow Airport says there has been a 52 per cent drop in outbound alcohol-related incidents, which it linked to the launch of One Too Many.

It recently emerged that World Duty Free, the biggest provider of duty-free shops at UK airports, now sells alcohol in sealed bags to prevent the contents being accessed before or during a flight.

The bags require a sharp object to get into and are labelled ‘do not open alcohol purchases until your final destination’.

Last November, the UK government launched a public consultation into airport alcohol licensing laws, saying it wanted to reduce disruption caused by drunk passengers.

Airside pubs, bars, restaurants, lounges and shops at international airports in England and Wales are not subject to the 2003 Licensing Act, which the government said meant they could sell to visible drunk people and promote “irresponsible” deals.

It also cited a 2017 survey by Unite of 4,000 cabin crew working for British-based airlines, which found that 87 per cent of respondents had witnessed drunken passenger behaviour at UK airports or on flights from UK airports.

Karen Dee, Chief Executive of the Airport Operators Association, commented: “The One Too Many campaign has returned to remind passengers of the penalties they face.

“However, the industry itself needs no reminder. Airport and airline staff are always ready to act to prevent or deal with a disruptive incident and will not hesitate to action the deserved penalties.

“We hope those departing from the UK’s airports this summer fly responsibly and start their party at the destination, not onboard.”
