Jet2 and Jet2CityBreaks is expanding a newly-introduced Iceland programme.
More flights are being added from Leeds Bradford and Newcastle airports due to demand.
New short breaks have been added from both bases just weeks after the Iceland programme went on sale.
The expansion means a total of 12 trips are now available from Birmingham, Glasgow, Leeds Bradford, Manchester and Newcastle in February and March.
All flights to Keflavík International airport near Reykjavik will be operated by Boeing 737-800s.
CEO Steve Heapy said: “These additional trip to Iceland and the Northern Lights come in direct response to the demand we’ve seen from customers since launching just a few weeks ago.
“We are thrilled with this response, and we are now offering customers even more choice when it comes to visiting this wonderful country.
“Iceland is home to many natural and unique wonders, from the Northern Lights to natural parks and geothermal spas, and we can’t wait to welcome customers on these trips-of-a-lifetime with us next year.”
