Less than four months after its maiden flight, Bombardier’s CS300 is set to make its air show debut at the world’s premier aviation event in Paris this month.

The long-delayed airplane, designed for the 100- to 149-seat, single-aisle market, is expected to enter service in late 2016.

Bombardier believes the CS300 offers the best seat-mile cost in its category and is ideal for a range of routes from short-haul to longer transcontinental markets.

Test flights for the smaller CS100, which can carry up to 125 people, began in 2013.

Certification for that aircraft is expected in the second half of this year with commercial flights starting shortly after that.

Bombardier has won 243 firm orders for the CSeries aircraft, 180 of them for the CS300.

The 51^st edition of the Paris Air Show opens on June 15. The week-long event has attracted more than 2,200 exhibitors from 45 countries including 18 from Canada.

The United States will have the biggest presence – more than 350 companies will gather at the American pavilion.

In all, 150 aircraft will be on display at the show and 40 of them will take to the skies of Le Bourget.

 “Paris Air and Space Show is a major player in the aerospace industry, and shows its richness and diversity,” says Emeric d’Arcimoles, the show’s chairman and CEO.

“More than just a showcase, the show is an extraordinary exchange tool, in which every actor of this industry finds the contacts and ideas that will help them to grow.”
