Boeing has delivered the 300th Next Generation 737-800 to Europe’s largest low-fare carrier, Ryanair.

The airline will take delivery of a total of 37 of these aircraft during 2011 and is the world’s largest operator of the 737-800.

Ryanair took delivery of its first 737-800, which seats 189 passengers, from Boeing in 1999. 

Ryanair’s chief executive, Michael O’Leary, said: “We are proud to take delivery of our 300th brand new Boeing 737 aircraft.

“We are proud to operate the youngest, greenest and most fuel-efficient fleet of any major European airline.”

The total value of the Ryanair fleet now stands at over $18 billion.

“The milestone delivery of this 737-800 to Ryanair is a tribute to the 737 and the strength and sustainability of Ryanair’s business model,” said Marlin Dailey, vice president of sales and marketing for Boeing Commercial Airplanes.

“The 737 offers an unbeatable combination of economics that will continue to give Ryanair a competitive advantage in the marketplace.”

Ryanair operates more than 1,400 flights per day from 44 bases and 1,100+ routes across 27 countries, connecting 160 destinations.
