Southampton Airport has had 200,000 passengers using the airport in August this year, which is an increase of 11% on August 2012.
The most popular destinations people travelled to were European countries, with flights to Malaga, Faro and Verona being popular.
Flights to Jersey, Guernsey and Alderney in the Channel Islands were also very popular.
Dave Lees, Managing Director said, "There are a number of reasons for this strong growth in August.

Southampton Airport is undertaking a ground-breaking project to improve lighting on the aircraft stands as well as reduce carbon emissions.
The airport will make savings of around £45,000 by installing Light Emitting Diode (LED) lighting throughout the airport, cutting its electricity use by ten percent.
It is the first time LED technology has been used in this way at any UK airport.
The airport has replaced more than 70 per cent of its lighting with LED alternatives and also used solar powered technology across the airfield - cutting its electricity use by 10 per cent.
Airline operator Flybe has revealed that it is cutting up to 300 posts across the UK.
The company confirmed that some jobs will go at Southampton airport but added those losses would be in the "low teens".
Consultation will now take place with 250 staff at the Hampshire operation.
