Gatwick is poised for a record-breaking summer with 6.8 million passengers due to use the airport – up 3% on last year.
The busiest day for departures is due to be Friday July 31, when 150,000 passengers are expected.
The busiest week is forecast to be between August 10-16 when more than a million people will pass through the airport.
The top ten destinations are Barcelona, Malaga, Palma, Dublin, Faro, Alicante, Orlando, Madrid, Dalaman and Amsterdam.
Besides Orlando, the other top long haul destinations are Dubai, Cancun, Sharm el Sheik and Las Vegas.
Orlando sees growth in passenger numbers of 20% with the number of people travelling to Dubai up by 5%.
Nick Dunn, Gatwick Airport’s chief financial officer, said: “We fly to more destinations than any other London airport so we’re in an excellent position to offer the summer’s favourite holiday and business destinations.
“Our growth in both long haul and short haul services reflects that we are the only airport to serve all business models – full service, low-cost and charter – and provides a clear demonstration of the choice and value we offer passengers across the board.”
