More flights from Manchester and Stansted feature as part of an expanded Iceland programme by Jet2.com and Jet2CityBreaks for winter 2026-27.
Services from Birmingham, Leeds Bradford and Newcastle airports return, alongside departures from Bournemouth and Edinburgh.
Almost 65,000 seats have gone on sale with more than 170 outbound services scheduled.
The announcement follows the introduction of winter sun, cities and ski programmes for winter 2026-27.
Chief executive Steve Heapy said: “Our programme of flights and city breaks to Iceland continue to be hugely popular, thanks to its abundance of natural wonders, such as the Northern Lights, Golden Circle and Blue Lagoon.
“As well as these natural delights, Iceland also offers the ultimate city break destination in stylish Reykjavik, which is the world’s northernmost capital.
“Our winter ’26-’27 programme to Iceland provides customers and independent travel agents with a great choice of winter services and trips from across seven of our UK airport bases.
"As well as offering an unrivalled programme to Iceland, next year’s programme includes more flights on sale from two of our largest UK airport bases - Manchester and London Stansted airports.”
