The boost to the airline and operator’s winter 2024/2025 schedule comes in response to strong demand for trips and holidays to Iceland.
More than 30,000 seats are now on sale to the destination, representing a 13% increase on winter 2023/2024.
The programme will see Jet2.com and Jet2CityBreaks operate more than 170 outbound services between October 2024 and April 2025 from 10 UK bases.
Twice-weekly services have been put on sale from Bristol, Birmingham, East Midlands, Glasgow, Leeds Bradford, Stansted, Manchester and Newcastle airports, alongside a series of trips from Belfast and Edinburgh.
Steve Heapy, chief executive of Jet2.com and Jet2holidays, said: "Iceland is a destination that has continued to see strong demand due to its many stunning natural wonders, so we are delighted to be launching our biggest ever Iceland programme for winter 24/25.
"As well as offering more scheduled services and dedicated trips than ever before from 10 of our UK bases, we have also extended the season from Birmingham and Manchester and put on additional flying from Stansted and Bristol."
