Bombardier Commercial Aircraft president Gary Scott says more CSeries orders will be announced in the "not too distant future".
Giving a programme update to media attending the European Regions Airline Association general assembly in Barcelona, Scott said the manufacturer is in talks with "dozens" of potential CSeries operators.
"I would say we're in advanced discussions with a handful of those," says Scott. "We anticipate that these discussions will turn into orders in the not to distant future."
He declines to elaborate on the timelines and says the orders could be from virtually any corner of the world.
"The [CSeries] orders we've seen so far have been for 20, 30, 40 aircraft and these are representative of the kind of orders which are likely to continue," says Scott. "This is a new fleet type, so customers are looking at a significant number of aircraft."
He says the talks which are nearing competion are "not small orders". Most of them are for 10-12 aircraft.
