Thomas Cook Airlines has started its peaks campaign to highlight nine new routes for 2016.
The airline is offering £25 off a range of short and medium-haul flights; and £50 off long-haul flights.
Twice weekly flights from Gatwick to Orlando will operate on Wednesdays and Saturdays from May. A weekly service to Cayo Coco, Cuba, will also fly from the London airport on Sundays, while flights to Cape Town will operate on Mondays, Thursdays and Sundays from December 15.
Los Angeles, Boston and Tobago have also been added to the airline’s 2016 schedule and will be served from Manchester.
The Los Angeles service will operate on Mondays and Saturdays from May 2 and the Boston service on Mondays and Fridays from May 30. Manchester to Tobago will fly once a week on Sundays from November 13.
A weekly flight from Manchester to mid-haul destination Cape Verde has also been introduced for summer. The Sunday flight from Manchester to Sal will begin on May 1.
Other new summer destinations include Kavala, Thassos, which will fly from both Gatwick and Manchester on Fridays, and a twice-weekly service from Manchester to Alicante which will begin on May 22.
The airline has purchased four new Airbus A321 to service its new and existing routes for 2016.
A Thomas Cook Airlines spokesman said: “Most notable about our plans next year are the new long-haul routes to Cape Town, Tobago, Los Angeles and Boston because they depict the story of how the airline is growing its long-haul offer.”
