Porter to acquire two additional Q400s

March 31, 2008, Toronto – Bombardier Aerospace has announced that Porter Airlines of Toronto has signed a firm order contract for two 70-seat Q400 turboprop airliners.

The transaction represents the conversion of two of the 10 options taken by Porter when it placed a firm order for 10 Q400 aircraft in 2006, and brings the total number of firm Q400 aircraft orders placed by the airline to 12.

The value of the contract at Q400 aircraft list prices is approximately $51 million U.S.
Based at Toronto City Centre Airport on the city’s Lake Ontario waterfront, Porter Airlines began
flying to Montréal and Ottawa in the fall of 2006. It later added flights to Halifax and the resort
area of Mont Tremblant, Québec. Porter has recently announced that flights to New York via
Newark Liberty International Airport are scheduled to begin on March 31, 2008.

“The Q400 airliner is everything we thought it would be and we’re delighted to be expanding our
fleet,” said Robert Deluce, President and Chief Executive Officer, Porter Airlines. “The crews
like the way it flies, the passengers appreciate its cabin comfort, and we appreciate the low
operating costs.”

“This extraordinary aircraft sparked a resurgence in turboprop travel around the world,” said
Steven Ridolfi, President, Bombardier Regional Aircraft. “At 360 knots (667 km/h) the Q400
airliner combines jet-like speed with among the lowest operating costs of any regional aircraft.”
The order increases orders for the Q400 aircraft to 282, with 190 delivered as of January 31, 2008.
