The One Too Many campaign is now in its eight year.

The UK aviation industry has relaunched its Government-backed ‘One Too Many’ campaign for 2026, warning passengers that disruptive behaviour could result in significant fines, denied boarding, airline bans and even imprisonment.

Now in its eighth year, the initiative brings together the UK Travel Retail Forum (UKTRF), AirportsUK, Airlines UK and the International Air Transport Association (IATA) in a coordinated effort to promote responsible behaviour across the passenger journey ahead of the busy summer travel season.

The campaign comes as airports across the UK prepare for another peak period of passenger traffic, with more than 20 airports participating in the nationwide initiative. These include major hubs such as Heathrow, Gatwick, Manchester, Birmingham, Glasgow, London City and Liverpool John Lennon Airport.

Through a combination of airport advertising, digital communications and social media activity, the campaign aims to remind travellers of the potentially serious consequences associated with disruptive conduct before and during their journey. Messaging will appear across airport terminals, retail and food & beverage locations, digital screens and passengers’ personal devices, helping to ensure visibility at key points throughout the travel experience.

Passengers are being reminded that disruptive behaviour can lead to penalties including up to two years in prison for disrupting a flight, fines of up to £5,000 for delaying a departure and penalties of up to £80,000 if their actions result in a flight diversion. Airlines may also refuse boarding to passengers deemed unfit to fly and can impose lifetime bans in cases where behaviour leads to significant disruption or flight cancellations.

Keir Mather, Aviation, Maritime and Decarbonisation Minister, said: “Millions of people will travel through UK airports this summer, and everyone deserves to do so safely and without fear of other passengers behaving poorly. The vast majority of passengers behave responsibly, but incidents involving disruptive behaviour can have serious consequences for fellow travellers, crew and airport staff.

“That’s why we are proud to support the ‘One Too Many’ campaign once again, working closely with the aviation industry to remind passengers that anti-social, disruptive and dangerous behaviour will not be tolerated. By making the risks and consequences clear, we can help ensure journeys get off to the right start and that everyone can travel with confidence.”

UK Travel Retail Forum Chair Nigel Keal said the campaign is designed to support the overwhelmingly positive behaviour demonstrated by most travellers while helping to reduce incidents through greater awareness. “The vast majority of passengers travel responsibly and want to start their holiday in a positive way,” he said. “This campaign is about supporting that by helping people make informed choices and understand the impact their behaviour can have on others.

“Clear and consistent messaging plays an important role in helping prevent disruptive behaviour. By making expectations and consequences clear and visible, we can help ensure a smoother, more enjoyable journey for everyone.”

AirportsUK Chief Executive Karen Dee added: “Airports across the country are looking forward to welcoming holidaymakers as they embark on their well-earned summer break and preparations are underway for the big getaway. As part of this, we are delighted to support the One Too Many campaign as an important sector-led initiative that supports the responsible behaviour that helps everyone travel safely, in comfort and with as little disruption as possible.”

IATA Senior Vice President of External Affairs Thomas Reynaert described the initiative as a strong example of industry collaboration. “Passengers and airline crew expect a safe and comfortable flight, which is why the industry has a zero-tolerance approach to unruly and disruptive passenger behaviour,” he said.

“Tackling this issue requires a coordinated response. Clear expectations for passengers and robust deterrence are essential to preventing incidents before they occur. The UK’s One Too Many campaign is a successful example of industry cooperation to promote responsible behaviour and make clear the serious consequences of disruption, helping to keep travel safe and enjoyable for everyone.”

The campaign has become one of the aviation sector’s most visible examples of collaborative passenger education, bringing together airports, airlines, retailers and industry associations in a shared effort to support safer and more enjoyable journeys throughout the summer travel season.
