Nearly 13,000 people were adversely affected by the noise of Gatwick night flights in 2014 – a 15% rise on the previous year.
The figures, in a report by the Civil Aviation Authority, were revealed at a meeting of the Gatwick Airport Consultative Committee.
The CAA report also shows that the number of people who said they were more seriously affected by night time noise doubled in the past year.
Gatwick has recorded its busiest ever September, with four million people travelling through the airport.
Managers say they expect to hit another record this year, the 40 million annual passenger mark. They say it's another reason the site should be expanded instead of Heathrow.
A man who was tasered by police on board an aircraft at Gatwick airport has been detained under the Mental Health Act.
Sussex Police said the 37-year-old was taken off the easyJet flight to Belfast shortly after 8am yesterday after being arrested by firearms officers called to the aircraft by the crew.
The man, from Belfast, was arrested on suspicion of breach of the peace and obstructing/resisting a constable in the execution of their duty.
Earlier it was reported that the incident leading to the arrest was because he wanted to take two pieces of hand luggage on to the plane. Police said there were reports of a passenger who was becoming increasingly abusive following a dispute over luggage.
After the man was arrested, people were taken off the plane and witnesses gave statements to police.
"On Thursday evening, following examination by doctors, he was detained under Section 2 of the Mental Health Act for admission into a psychiatric unit for further assessment and treatment in the interest of his own health, safety and protection of others."
"EasyJet can confirm that police boarded flight EZY831 from London Gatwick to Belfast on August 20 due to a passenger behaving disruptively.
"EasyJet's cabin crew are highly trained to assess and evaluate all situations and to act quickly and appropriately to ensure that the safety of the flight and other passengers is not compromised at any time.
"Whilst such incidents are rare we take them very seriously, do not tolerate abusive or threatening behaviour on board and always push for prosecution.
"The safety and well-being of passengers and crew is always easyJet's priority."
A third runway at Heathrow would be "unlawful", its rival Gatwick claimed today.
It says expansion at Heathrow would breach strict European air quality limits. Gatwick, meanwhile, claims it would meet all limits with a second runway and expansion should be in Sussex.
But Heathrow has hit back saying it would put measures in place to mitigate and the airport is the best place for expansion with tens of thousands of new jobs boosting the local economy.
The row erupted on the final day of consultation on pollution by the Airport Commission, which will make a recommendation on a new runway at Heathrow or Gatwick in the next few weeks.
Sixteen people are due to appear before Crawley magistrates in connection with a plot to steal millions of pounds worth of cigarettes from a company at Gatwick Airport.
The fifteen men and one woman are accused of planning to take the tobacco worth a total of £2,432,665 from Gate Gourmet - a firm which supplies airlines at the airport.
It is the latest move in the battle between Heathrow and Gatwick as they both aim to win support for airport expansion.
Gatwick say expansion at Heathrow would lead to tens of thousands more people suffering aircraft noise. Heathrow say it has the best runway plan that would not see overall noise increase and create tens of thousands of jobs.
The Airport Commission will announce its recommendation in June.
Gatwick had a record breaking number of passengers in March. with two point nine six travelling through the airport.
It says it is now expecting to serve more than forty million people next year - a decade ahead of the predictions made by the Department for Transport.
