New routes from Edinburgh and Birmingham to the Canary Islands are being added by low-cost carrier Norwegian from the autumn.
Tenerife will be served from both airports while Birmingham will also gain a service to Las Palmas on Gran Canaria.
The three routes will operate year round using 186-seat Boeing 737-800s which provide free Wi-Fi for passengers.
The airline is also increasing frequency on services from Gatwick to Berlin and Rome.
Two daily flights will operate between Gatwick and Berlin on Mondays, Wednesdays, Fridays and Sundays, with daily flights to Rome.
The latest expansion follows the introduction of the first low-fare flights from Gatwick to San Juan in Puerto Rico last month.
Chief commercial officer, Thomas Ramdahl, said: “We are pleased to announce further growth in the UK with the addition of new, winter sun destinations from Edinburgh and Birmingham.
“Norwegian is committed to offering quality flights at affordable fares whether you are travelling to Scandinavia, Europe or further afield. Our network from the UK now extends to 58 destinations worldwide.
“We are looking forward to welcoming new and returning customers on our routes to the Canary Islands and San Juan in Puerto Rico from winter 2015.”
