Wizz Air is to start six Luton airport routes to Greece from July 16, the day after direct UK flights are permitted by the Greek government.
The budget carrier will serve Athens, Crete, Corfu, Zakynthos, Rhodes and Thessaloniki.
Athens and Crete flights start on July 16, followed by Corfu on July 18 and Rhodes, Thessaloniki and Zakynthos on July 19.
Fares lead in at £21.99 one-way to Zakynthos.
Meanwhile, low cost rival Ryanair is offering more than 500 routes to and from the UK as part of a revised summer schedule.
Fares are being cut by 15% on 500,000 seats for travel in August and Sept on bookings made by midnight on Thursday.
