The order is part of a contract announced on March 30, which includes 20 firm and 20 option aircraft.
Adam Tomazos, LCI chairman, said: ‘We are excited about the future of Bombardier’s CSeries jetliner family.
‘Market studies carried out by ourselves and other organisations see a large worldwide demand for aircraft in the 100- to 149-seat category over the next two decades, and the CSeries jetliner family is a perfect fit.’
Todd Kallman, president, Pratt & Whitney Commercial Engines and Global Services, said: ‘This order, along with Lufthansa’s firm order earlier this month, gives Pratt & Whitney the opportunity to provide up to 200 PW1000G engines for Bombardier CSeries aircraft.
‘Our engines will help our customers with double-digit reductions in fuel burn and operating costs.’
The deal will be the third order for the Pure Power PW1000G engine, which also powers the Mitsubishi Regional Jet that received its launch order from All Nippon Airways in 2008.
The aircraft are scheduled to enter service in 2013.
