Latvia's airBaltic has placed a firm order for 10 C-Series jets from Bombardier Inc., with an option for up to 10 more, the Canadian aircraft and train maker said on Thursday.
Bombardier said in a statement that the deal is worth about $764 million, or up to $1.57 billion if all of the options are exercised.
The Montreal-based company, which delayed the first flight of the new C-Series aircraft in November, has seen sluggish demand for the jet to date.
The C-Series is Bombardier's biggest aircraft yet, and competes with smaller regional planes built by industry giants Airbus and Boeing Co.
Shares rose 1.4 to C$3.62 in early trading on the Toronto Stock Exchange.
