SEOUL ( TheStreet) -- China Eastern Airlines cancelled an order for 24 Dreamliner 787 jets from Boeing ( BA) but Boeing said its order book for the plane remains strong. China Eastern said Monday it would instead buy 45 of Boeing's smaller 737 aircraft for $3.3 billion. It also said it would purchase 15 A330s from Airbus, Boeing's rival. "Frankly as we look forward, we expect to see the Dreamliner order base increase, we expect to see more orders, we expect to see more cancellations, especially as we go through mitigation with our customers," Boeing marketing vice president Randy Tinseth said, according to a Reuters report. Boeing's first 787 Dreamliner took off for Japan late last month, after the company handed the plane over to debut customer All Nippon Airways. The first aircraft originally was scheduled to be delivered in May 2008. -- Written by Joseph Woelfel >To contact the writer of this article, click here: Joseph Woelfel >To submit a news tip, send an email to: firstname.lastname@example.org.
