On April 25, the Boeing Company confirmed an order by Air Canada, announced April 24 by the airline, for 23 Boeing 787 Dreamliners. The order brings to 37 the number of 787s ordered by the airline. Air Canada has ordered more Dreamliners than any other carrier in the Western Hemisphere.

The 23 787s are worth approximately US$3.5 billion at list prices. The order brings the total number of announced firm 787 orders to 567 from 44 customers. As part of today's deal, Boeing and Air Canada agreed to cancel two 777 freighter orders.

"Air Canada will be among those airlines prepared to provide passengers with the most modern flying experience possible using the 787 -- higher cabin humidity, large windows, a lower cabin altitude and more cabin space," said Ray Conner, vice president, Sales, Boeing Commercial Airplanes.

Air Canada was the 25th airline to select the 787 Dreamliner when, in 2005, it ordered 14 ultra-efficient 787s.
