The airline and operator will start flying to Rhodes from 2 April and to Halkidiki from 1 April after the brands reported an uptick in demand from customers looking to travel earlier next year.
The extended summer season to Rhodes will come into effect from two UK bases, with flights now commencing from Birmingham on Thursdays and Sundays from 2 April and Manchester on Mondays and Fridays from 3 April.
In addition, Jet2.com and Jet2holidays are operating flights and holidays to Rhodes throughout next summer from Belfast, Bristol, East Midlands, Edinburgh, Glasgow, Leeds Bradford, Newcastle and Stansted airports.
Meanwhile, flights and holidays to Halkidiki will now start from 1 April from Manchester and Stansted on Tuesdays and Saturdays, with weekly Friday services starting from Birmingham on 7 April.
Steve Heapy, chief executive of Jet2.com and Jet2holidays, said: "Rhodes and Halkidiki are enormously popular destinations, and there is great demand from customers and independent travel agents looking to book or travel earlier in the summer season or getaway at Easter.
"As the UK’s leading airline and tour operator to Greece, we have reacted to that demand and extended the summer 23 seasons to Rhodes and Halkidiki, providing customers with the holiday choices that they want."
