The Greek islands of Corfu, Crete, Mykonos and Santorini will gain new flights from the UK this summer.
Aegean is launching new routes to the islands as well as a service to Thessaloniki on the mainland.
Mykonos and Santorini will gain routes from Heathrow with up to three flights a week as well as Heraklion with a daily connection and Thessaloniki with up to three flights a week.
Four flights a week will run from Gatwick to Corfu.
All will operate between May 17 and October 31 with the exception of the Heathrow-Myknonos service which is scheduled to run from June 19 until September 18.
Promotional fares start at £44 one-way to Corfu for bookings made by April 5.
The Greek carrier said the summer schedule aimed to “facilitate conditions for a fast recovery of the tourist industry” this summer.
The new services are in addition to existing flights from Heathrow to Athens and summer links to the Greek capital from Edinburgh, Manchester and Dublin.
