Sept 26 (Reuters) - The head of Indonesia's Lion Air, one of the world's fastest-growing low-cost airlines, expressed interest on Thursday in buying a larger version of Bombardier's

BBDb.TO CSeries jet.

The 130-seater will be a bigger-capacity version of the CS100, which staged a maiden flight earlier this month as Canada

aims to break into a market dominated by Airbus and Boeing.

"I am ?nterested in buying the CS300. We will know how many after we learn about ?t more deeply," co-founder and chief executive Rusdi Kirana said by email.

"I th?nk it w?ll su?t our operat?on," he added.

The privately owned Indonesian carrier has already placed record orders for Boeing BA.N and Airbus EAD.PA jets to serve the archipelago nation's rapid air traffic growth.
