LONDON: Budget carrier Ryanair PLC has stopped discussions to purchase as many as 200 new Boeing 737-800 aircraft after being unable to extract concessions from the manufacturer.

Ryanair chief executive officer Michael O'Leary said Friday that pricing for the aircraft — which were to be delivered between 2013 and 2016 — had been agreed, but that Boeing was "unwilling to incorporate some other terms and conditions" in the order.

He said it's unlikely the company will reopen negotiations with Boeing or any other manufacturer.

"Instead we will focus our efforts on maintaining Ryanair's strong traffic and new route growth into 2010," O'Leary said. "We look forward to briefing shareholders in the first quarter of the New Year with a revised strategy which will comprise much reduced capital expenditures through 2011 and 2012."

However, the airline will still take delivery of 112 Boeing 737-800s over the next three years. Ryanair is one of Boeing's biggest customers.
