The first scheduled flight will be LX638 from Zurich to Paris Charles de Gaulle next July 15.

The carrier also informed that the Zurich - London City CSeries service is expected to take place from the first quarter of 2017.The last month, Bombardier completed the European route-proving program of its CS100, including more than 30 city-pairs. The program, which lasted three weeks, included flights to several major cities. At that time, Peter Wojahn, Chief Technical Officer, SWISS said “the route-proving program provided us with a real indication of how the CSeries will operate in our route system (…) [and] we are very pleased and impressed with the results.”https://www.youtube.com/watch?v=ywWi11YHB7wThe CS100 conducted flights using standard airline flight operations and routes, with no passengers onboard. The program provided data on the behavior and performance of the new jetliner under a typical airline schedule to and from different airports. Airfield performance, landings, airport turnarounds and on-ground operations are some of the characteristics observed.SWISS is currently undergoing a major fleet renewal. This year, the carrier took delivery of its first Boeing 777-300ER. By the end of August, SWISS will have received five more Boeing 777s of an initial order of nine, intended to replace part of its aging Airbus A340-300 fleet.
