Bombardier and Swiss International Air Lines (SWISS) announced on May 7, 2015 that SWISS will be the first customer to take delivery and operate the CSeries aircraft when the CS100 aircraft enters service with the airline in the first half of 2016.
Bombardier also confirmed that the CSeries will make its world debut at the International Paris Air Show being held at Le Bourget, France and will fly directly to Zürich, Switzerland in June as part of a demonstration tour.
SWISS was previously announced as the launch customer for the CSeries aircraft program after parent Deutsche Lufthansa AG signed a firm purchase agreement in 2009 for 30 CS100 single-aisle aircraft to be operated by SWISS.
Bombardier has booked orders and commitments for 603 CSeries aircraft, which include firm orders for 243 CSeries aircraft.
