And the destinations you can fly to from there are the coastal resorts of Bodrum, Dalaman and Antalya, when changing at Istanbul Sabiha Gökçen Airport.
To take advantage of the cheap flights, Brits have to sign up to the airline’s loyalty programme BolBol, although this is free.
The flights don’t include taxes and have to be booked either today or tomorrow.
However, travel can take place anytime between March 30 and October 2025 next year.
The cheapest fares are likely to sell out quickly, with 200,000 seats on offer.
The tickets are part of the airline’s Light package which only includes an underseat bag.
But you can easily add checked luggage for just €5 (£4.20), as part of the deal.
Jet2 also launched more flights to Bodrum this year, extending into the winter season.
Antalya
Antalya welcomes more than one million Brits a year.
Beaches follow the city’s crescent-shaped bay, with a pebble beach and crystal-clear water along the flank bordering the new city and a long expanse of sand stretching away from the picturesque old port.
It is home to the the Land of Legends theme park — visible for miles around thanks to its towering Disney-style castle.
Dalaman
Dalaman’s famous attraction is the rock tombs of Fethiye, built into the huge cliff faces.
