For years the Canadian company Bombardier has endeavored to design and build a state-of-the art, single-aisle passenger aircraft. With its C Series, it looks as though it has succeeded, which is good news for the flying public and airlines. Boeing, however, is not happy.

After Delta Airlines placed an order for 75 of Bombardier’s new C Series, Boeing charged Bombardier with unloading the planes in the U.S. at below-cost prices. In fact, it has now asked the U.S. International Trade Commission to lay anti-dumping and countervailing duties against the C Series.
