London: Irish no-frills airline Ryanair announced on Tuesday that annual net profits surged by two thirds, boosted by improved customer services, rising sales and sliding oil prices.

Earnings after taxation leapt 66 per cent to €866.7 million ($944.1 million; Dh3.49 billion) in the year to March 31, compared with €522.8 million in 2013/2014, Ryanair said in a results statement.

That beat the company’s own guidance of between €840 million and €850 million.

Passenger numbers swelled by 11 per cent to stand at 90.6 million customers, and revenues grew 12 per cent to €5.654 billion.

Chief executive Michael O’Leary said the group’s ‘Always Getting Better’ customer services programme “has attracted millions of new customers to Ryanair”.

The airline also forecast that 2015/2016 net profit would climb to a range between €940 million and €970 million.
