Aviation History
Swiss commercial aviation traces back to early carriers such as Ad Astra Aero, founded in 1919, which merged with Balair in 1931 to form Swissair. Swissair grew into one of the world's most respected airlines, nicknamed "the flying bank" for its reputation for financial soundness, and Zurich's Kloten Airport, opened in 1948, became its main hub. An aggressive late-1990s expansion strategy of buying stakes in struggling foreign airlines left Swissair overextended, and on 2 October 2001 the carrier grounded its entire fleet after running out of cash, a national shock that led to bankruptcy. Crossair, a regional carrier majority-owned by Swissair and founded in 1975, absorbed key assets and relaunched in 2002 as Swiss International Air Lines, which became a wholly owned subsidiary of Germany's Lufthansa Group later in the decade. Switzerland today remains an important business-aviation and hub-airline market despite its small size and position outside the European Union.
One of Switzerland's earliest airlines was established, later becoming one of the two carriers that merged to form Swissair.
Ad Astra Aero and Balair merged to form Swissair, which became Switzerland's flag carrier and grew a reputation as one of the world's most reliable airlines.
Zurich's Kloten Airport opened and became Switzerland's principal international hub.
A regional carrier majority-owned by Swissair was launched, later playing a central role in Swiss aviation after Swissair's 2001 collapse.
On 2 October 2001, Swissair grounded its fleet after running out of cash to pay for fuel, the culmination of an over-extended expansion strategy; the airline entered bankruptcy soon after.
Crossair absorbed Swissair's remaining viable assets and relaunched as Swiss International Air Lines, becoming Switzerland's new flag carrier.
Swiss International Air Lines became a wholly owned subsidiary of Germany's Lufthansa Group, integrating into one of Europe's largest airline groups while retaining its own brand.
