The low-cost carrier is also offering flights from Birmingham to the French city of Nantes, with its expanded schedule following new summer services to Faro, Malaga and Palma.
Around 100,000 seats have gone on sale, and package holidays are available through easyJet holidays.
EasyJet claimed its new Greek routes for summer 2022 meant it was set to carry more passengers from the UK to the Greek islands than any other airline.
The carrier has also boosted its capacity from Gatwick, Luton, Bristol, and Manchester to other Greek destinations including Santorini, Mykonos and Rhodes.
