The new programme will see almost one million extra seats, meaning an 11% increase in capacity.
A fleet of 82 aircraft will support the company’s biggest-ever flying programme, which covers 57 destinations and 292 routes in total.
Jet2.com and Jet2holidays will operate more than 2,000 weekly flights at peak times and more than 50,000 flights in total, giving holidaymakers more frequency and more flexible durations.
Changes include “significant expansion” of Halkidiki and Costa de Almeria. Both destinations will be available for the first time with Jet2.com and Jet2holidays for summer 2017 and are seeing growth for 2018.
