Norwegian Air has revealed proposals for new flights from Edinburgh to a range of American destinations.

The airline, which is Europe's third-largest low cost provider, outlined its  expansion plans during a visit to the city on Wednesday.

Flights to destinations including Boston, New York and San Francisco are being considered by Norwegian Air, with prices starting from £200 return.

Washington DC is also being considered by the airline as it prepares to offer its first low-cost long haul flights.

Chief executive Bjorn Bjos spoke as the Oslo-based firm reached its one million passenger milestone at Edinburgh Airport for existing routes to Scandinavia, Spain and the Mediterranean.

Speaking at a conference in Edinburgh, Mr Bjos said he backed the expansion of Gatwick Airport as would help all UK airports to grow and given more choice for Scots.

He was joined by Gordon Dewar, chief executive of Edinburgh Airport, and Gatwick's Stewart Wingate to make the case for a "more competitive" UK airports sector.

Mr Kjos said: "Since we started flying from Edinburgh in 2009, we have grown to six routes and have now carried over one million passengers - but this is only the beginning of our plans for expansion.

"Edinburgh will play an important role in our future UK growth and our long-term ambition is to deliver new, direct long haul flights from Edinburgh.

"We will also be looking into how we can create new routes from Edinburgh to feed into our fast-growing global network at London Gatwick, which would further boost the choices available to Scottish passengers."

He added: "We look forward to continued growth at Edinburgh Airport including plans for our first low-cost long-haul routes in the future."

Mr Wingate said: "The success of Norwegian Air in recent years, particularly at Gatwick and Edinburgh, illustrates very clearly the fundamental changes that are taking place in the aviation world."
