DUBAI, United Arab Emirates (AP) — FlyDubai, the lower-cost sister carrier of Emirates, said it ordered 75 additional Boeing 737 MAX aircraft in a deal worth $13 billion.

The announcements came after FlyDubai earlier at the Dubai Air Show made a major Airbus A321neo purchase of 150 aircraft for $24 billion. Since its first flight in 2009, FlyDubai had only flown Boeing 737s, making the sale a major win for the European consortium at the biennial air show.

“Looking ahead, proactive fleet planning is essential to ensuring we are well-placed to meet the rising demand for travel, a demand we are confident will continue to grow,” said Sheikh Ahmed bin Saeed Al Maktoum, the chairman of both FlyDubai and Emirates. “Anticipating future needs is a defining factor in the success of any airline and today’s announcement reflects our commitment to that principle.”

FlyDubai and Boeing made the announcement in statements without a news conference.

“We are proud that Boeing airplanes will continue to serve as the backbone of FlyDubai’s strategic fleet and growth plans,” Stephanie Pope, president and CEO of Boeing Commercial Airplanes, said in the same FlyDubai statement.

FlyDubai added it had options for an additional 75 Boeing aircraft as part of the deal.
