Malta, Naples and Nice are being added as new destinations from Stansted by Jet2 and Jet2holidays as part of an expanded summer 2018 programme from the airport.
Capacity is being raised by 200,000 seats as the sister airline and tour operator cover a total of 33 destinations from the Essex airport.
This growth means that capacity has been hiked by 60% to more than 1.4 million seats for its second summer of operations from Stansted.
More weekly flights are being laid on to a number of destinations, including Turkey, Gran Canaria, Menorca, Girona, Paphos, Dubrovnik and Verona.
Ten aircraft will operate from the airport next summer, up from seven this year.
Chief executive Steve Heapy said: “We have experienced a fabulous response to our flights and holidays from independent travel agents since putting our summer ‘18 programme on sale from Stansted airport.
“With 33 destinations on sale, in just our second summer of operations, this reflects the confidence we have at our newest base – where our offer of real package holidays is making us a huge hit.”
