Three-month TSX trading in Bombardier class B shares

Bombardier Aerospace has a $3.1 billion US deal to sell 40 of its CS300 jet airliners to Republic Airways Holdings, a U.S. operator of 1,600 daily flights under half a dozen different airline names.

There is a firm deal for 40 of the planes, and an option on another 40, Montreal-based Bombardier said in a news release Thursday. If the option is exercised, the deal will be worth $6.3 billion US to Bombardier.

With the Republic order, Bombardier now has 90 firm commitments for the longer-range, economical and low-emission planes.

Bombardier class B shares closed up 39 cents at $5.87 on the Toronto Stock Exchange. The price is a 52-week high.

Deliveries will start in 2015, Republic said. The planes will be configured as a single cabin for 138 passengers.

"The CS300 will help us dramatically reduce our fuel consumption and impact on the environment," Bryan Bedford, chairman, president and CEO of Republic, said in a news release. 

Republic, based in Indianapolis, operates 283 planes and owns Chautauqua Airlines, Frontier Airlines, Lynx Aviation, Midwest Airlines, Republic Airlines and Shuttle America.
