EasyJet is extending its summer routes from Northern Ireland into the winter.
More than 83,000 seats are being made available on at least 460 flights.
Services from Belfast International airport to Leeds-Bradford and East Midlands, as well as from Belfast City to Gatwick will operate throughout the winter months to serve demand.
Fares start at £22.99 one-way.
The move follows Aer Lingus increasing services from Belfast City this winter to Heathrow, Manchester and Edinburgh.
EasyJet UK country manager Ali Gayward said: “We are delighted to see our new routes from Belfast International airport to Leeds and East Midlands, as well as from Belfast City to London Gatwick proving popular for our leisure and business customers alike.
“To serve continued demand we are pleased to confirm that these services will continue operating into the winter months, with great value fares now available.
“We continue to have some of the most flexible policies currently in place so customers can book with confidence and change their plans if they need to, making travel as easy as possible this winter.”
