Airbus Group NV raised the prospect of discontinuing its A380 superjumbo as soon as 2018, the first admission that it may have misjudged the market for the double-decker after failing to find a single airline buyer this year.

While Airbus will break even on the plane in 2015, 2016 and 2017, that outlook doesn't hold for 2018, forcing the company to either offer new engines to make the A380 more attractive or discontinue the program, Chief Financial Officer Harald Wilhelm told investors at a meeting in London on Wednesday.

His comments come as 2014 shapes up to be the first since the doubledecker entered service without a new airline customer. Its only buyer was a leasing company that has yet to line up a single carrier to take any of the 20 planes it ordered. The backlog remains as thin as it is fragile, highlighted by the cancellation of six jets ordered by Japan's Skymark Airlines Inc., with two close to handover.
