Colgan Air options 15 more Bombardier airliners

(In U.S. dollars)

TORONTO Feb 9 (Reuters) - Bombardier Inc (BBDb.TO) said on Monday its aerospace division has finalized terms on U.S. regional airline Colgan Air Inc's option to buy another 15 of Bombardier's Q400 NextGen turboprop airliners, on top of the 15 firm orders announced in January.

On Jan. 15, Colgan Air ordered 15 of the fuel-efficient, low emission, 70- to 80-seat turboprops airliners for a total of about $432 million.

Colgan Air is a subsidiary of Pinnacle Airlines Corp (PNCL.O).

Montreal-based Bombardier is the world's third-largest maker of civil aircraft and biggest maker of rail equipment.

Its shares have been under pressure lately, dropping around 20 percent so far this year, as the corporate jet market deteriorates due to the weak economy.

Bombardier shares were up 11 Canadian cents, or 3.2 percent, at C$3.58 on the Toronto Stock Exchange on Monday morning.
