Boeing will build a new version of its top selling Boeing 737 that squeezes in more seats, with budget airline Ryanair the launch customer.
The airline has committed to buy 100 737 MAX 200s valued at US$11 billion at current list prices, although the final price for the planes is likely to be different to that given the bulk order. It has options to double that order as it expands its fleet to 520 in the next decade, capable of carrying 150 million passengers a year, up from 86 million a year at the moment.
The new Boeing plane competes against the latest models of the Airbus A320, popular with airlines in this area, but has more seats.
The 737 MAX 200 will hold up to 200 seats, 11 more than the biggest 737 at the moment, although Ryanair will have seats for 197 passengers.
Boeing says at 200 seats the plane can increase revenue potential and provide up to 20 per cent better fuel efficiency per seat than the most efficient single-aisle airplanes.
