Bombardier says it will proceed with the first test flight for its new CSeries jet today, at an airport just outside Montreal.

The test was supposed to happen earlier this week, but was postponed because of inclement weather.

The Montreal-based company said early Friday that the CS300 will have its first test flight sometime Friday after getting Transport Canada's OK. The regulator's permission was an important final hurdle before Bombardier could get its much-anticipated jet into the skies.

Bombardier has more than 240 firm orders for its next-generation jet, which has been plagued by delays.
