The story
In 1998, Crossair launched Crossair Europe, as a subsidiary airline, operating flights from the French side of EuroAirport to circumvent challenges of European Union restrictions on Swiss air traffic and routes. Initial flights were offered to Marseilles, Milan and Venice, starting in April 1998. Swissair held a majority stake of 60% in the new airline, whilst Crossair retained 40%. Initially Crossair Europe operated dry-lease Saab 340B aircraft, later moving to the larger Saab 2000 models. The airline helped boost Crossair's 1998 passenger total to a record 4.43 million. In combination with Crossair, Swissair boosted destinations served from Basel to 71 in 2000 (up from 39 Crossair destinations in 1990).
When Swissair became Swiss International Airlines, Crossair Europe remained owned by the new airline as the 99.9% shareholder. In March 2005 it was announced that Crossair Europe would be closed by the end of the month and their routes were taken over by Swiss.
