Holidaymakers are being warned they could be jailed and fined tens of thousands of pounds if they get drunk and cause chaos on flights.
The aviation industry launched its summer 2019 One Too Many campaign on Friday, reminding passengers of the serious consequences of being disruptive on planes and at airports.
Warnings are being posted on digital display screens in shops and food outlets at 14 UK airports.
The campaign was first launched in summer 2018.
Disruptive passengers risk being handed a fine of up to £5,000 or a two-year prison sentence.
If they cause a flight to be diverted they can also be fined up to £80,000 to cover additional costs.
Four men on a drunken stag party were jailed at Manchester Crown Court on Tuesday after fighting and using bad language on a Thomas Cook Airlines flight from Manchester to Las Vegas.
Civil Aviation Authority figures show the number of disruptive passenger incidents in 2018 fell from 417 to 413 year-on-year, but some regional leisure routes saw an increase.
About a third of incidents are believed to be linked to alcohol.
Don’t join the tiny minority who has #OneTooMany when flying – it's not fair on other passengers and staff. You could be denied boarding, fined up to £5,000 or even sent to prison. https://t.co/yh2uvTvHSv#happyholidaysforallpic.twitter.com/NOjqyW7nQK

Aviation Minister Baroness Vere said: “The vast majority of passengers enjoy themselves responsibly, but there are a small minority that can make flying unpleasant or unsafe for others.
“We are clear this will not be tolerated.”
Tim Alderslade, chief executive of trade body Airlines UK, said: “We’ve seen some terrible incidents recently.
“Airline crew have a hard enough job as it is and they should not have to put up with the kind of behaviour we are seeing all too frequently.
“Carriers are the ones who have to bear the brunt of drunk and loutish behaviour and we will not hesitate to prosecute or issue lifetime bans if we deem it necessary.”
