OK, we’re calling it: the British summer is officially over.

After months of grey skies and spontaneous downpours, we’re getting ready to embrace all that autumn has to offer, while easing our vitamin D deficiencies with essential “back to school” stationery purchases and copious amounts of hot chocolate.

But if you’re not quite ready to venture into the chillier temperatures that September, October and November have to offer, fear not, for Norwegian Air has just kicked off its official autumn sale, and the discounts for cheap flights to winter holiday destinations, including flights to New York, are pretty epic.

Making the prospect of a winter break just that much more affordable, the airline’s slashed prices mean flights from the UK to the US are being offered for as little as £99 each way, the Mirror reports.

US destinations in the sale include New York, LA, Las Vegas, Orlando and San Francisco, so if you’ve ever fancied visiting one of these iconic locations, now is your time.

Plus, the airline is offering budget long-haul flights from London Gatwick to Singapore from £159.90 each way (at the time of writing), as well as cheap short-haul flights, including travel to a variety of destinations in Europe from £29 each way.
