Coin Press - Ryanair says Boeing delivery delays costing it millions of ticket sales

He also said the drop in ticket prices that dragged down Ryanair's first-half results should moderate later this year.

"Boeing delivery delays are challenging our schedule growth this year," O'Leary said at a press conference in London, saying Ryanair would transport five million fewer passengers this year than the 205 million it initially expected.

Ryanair has 350 Boeing 737 single-aisle planes under order, but the US manufacturer has delayed deliveries because of a series of technical problems.

"We were supposed to get seven in July. We got five. We were supposed to get ten in August. We're going to be lucky if we get five," he said. "It is very frustrating dealing with Boeing at the moment."

O'Leary said the five million fewer passengers could cut revenue by about 500 million euros ($550 million) this year.

"Boeing are certainly paying us some modest amounts of compensation, but I'd far rather have taken the aircrafts and grown even faster," he said.

The low-cost airline was also hit in the first half by prices declining about 15 percent on average from a year earlier, blaming high interest rates that cut into the disposable income of its clients.

"Good news for our customers, bad news for our shareholders," O'Leary said Tuesday.

But he said the declines were slowing, and for the full year prices would probably be down about five percent.
