EXTINCTION Rebellion members plan on targeting Gatwick Airport tomorrow morning - with eco-warriors being urged to cause "mischief" to passengers.
Extinction Rebellion protesters aim to arrive at the South Terminal at 11am and their presence is likely to spark travel chaos for holidaymakers.
Posting on the group's Telegram broadcast channel, one member urged others to "come incognito" and then "reveal yourself" after a signal is given.
They said that "musicians, clowns and singers" are welcome and added that "some people may like to indulge in a bit of mischief".
Their post read: "We're going on a trip to Gatwick Airport!
"With a light-hearted, informative vibe, lets give a wake-up call (again) about the urgent need to reduce the number of flights, not expand airports.
MISCHIEF
"We call on passengers and friends to join us in tackling the Climate and Ecological Emergency.
"They have the opportunity to contribute to safeguarding our future by limiting air travel to just essential journeys. Let’s make them welcome.
"Come incognito and await the signal at 11am to reveal yourself!
"Performers, musicians, clowns, singers, party hats welcome. We will be handing out leaflets encouraging people to play their part in what lies ahead.
"If inclined, some people may like to indulge in a bit of mischief but the intention is not to cause people to miss flights. Fun and imagination welcome.
"Though we can’t know what line the police or airport staff will take, so far as we know there is nothing in what we have outlined that would be against airport byelaws."

Extinction Rebellion
It comes after thousands of protesters have caused chaos and brought parts of London to a standstill following more than a week of disruption in the capital.
The group's co-founder Gail Bradbrook was arrested yesterday morning for smashing a window at the Department of Transport with a hammer and screwdriver.
Climate change protesters have been told to leave Trafalgar Square where many have congregated lawfully since Monday last week.
But despite the city-wide ban, the activists continued with their demonstrations on Tuesday morning.
The group called on ministers to stop funding "destructive" projects such as the new high-speed rail route HS2 and airport expansion.
1,445 ARRESTS
Police said 1,445 people had been arrested during eight days of protests in London.
Metropolitan Police Deputy Assistant Commissioner Laurence Taylor said: "After nine days of disruption we felt it is entirely proportionate and reasonable to impose this condition because of the cumulative impact of these protests."
Police are facing growing criticism over the London-wide ban on Extinction Rebellion protests.
In response Shadow Home Secretary Diane Abbott said the ban was "completely contrary to Britain's long-held traditions of policing by consent, freedom of speech, and the right to protest".
London Mayor Sadiq Khan added: "I believe the right to peaceful and lawful protest must always be upheld."
WHO ARE EXTINCTION REBELLION?
Extinction Rebellion is calling on the Government declare a climate and ecological emergency, act immediately to halt wildlife loss and reduce greenhouse gas emissions to net zero by 2025.
Earlier in the year, Parliament declared a climate and environment emergency and the Government has passed a law to cut emissions to net zero by 2050, far later than the activists are demanding.
The group staged 11 days of protests in London in April that disrupted public transport and roads.
On Thursday Extinction Rebellion activists used a fire engine to hose red liquid at the Treasury to draw attention to what they said was the government's failure to avert climate disaster.
Last week the Met warned that the protests were taking officers away from other vital roles in the capital including tackling knife crime and domestic violence.
More resources have been used policing climate change protest than focusing on terror, it was said.
