A top executive at Bombardier has remained tight-lipped over whether the new CSeries aircraft, the wings of which were designed and are being built in Belfast, will be on display at the Farnborough International Airshow.
The planes are expected to enter service in 2015 after a series of delays.
Orders stand at around 200 and confirmed customers include Lufthansa, Gulf Air, Korean Air, airBaltic and Iraqi Airways.
Bombardier Commercial Aircraft president Mike Arcamone was speaking at the Aviation Club of the United Kingdom on Thursday in London's Pall Mall.
Talking about the CSeries, he described the jet as "gamechanging" but refused to confirm if the planes would be displayed at Farnborough Air Show in July.
The Farnborough International Air Show takes place biennially alongside Paris Air Show and is recognised as a top industry showcases for the major global aerospace buyers and sellers.
