The UK's largest airline will offer services to Alicante, Malaga and Faro as well as city break destinations Edinburgh, Barcelona and Helsinki.
Commenting on the schedule's launch, David Osborne, easyJet's regional general manager for the UK, said: "easyJet is committed to bringing more and more low cost air services to an ever increasing number of customers across Europe.
"The attractiveness of our fares and the airports we serve make easyJet the number one choice for travellers in the south-east."
As well as launching its summer schedule, easyJet has said that it will shortly announce the launch of new routes from its base at London Gatwick.
The airline said last week that it would be offering passengers stranded in Bangkok a special rescue fee of £35 to return to the UK.
The fee includes taxes and charges and will be reviewed on a weekly basis.
