About SWISS
SWISS, formally Swiss International Air Lines, is the national airline of Switzerland. Zurich is its hub and Geneva its second base. The carrier is owned by the Lufthansa Group and is a Star Alliance member, so its schedules and codeshares are closely tied to Lufthansa, Austrian Airlines and Brussels Airlines. From Zurich it flies throughout Europe and to North and South America, Africa, the Middle East and Asia. Long-haul aircraft are fitted with First, Business, Premium Economy and Economy cabins, and European flights carry Business and Economy.
Travel agents and developers can search SWISS on IATA.co through the booking portal or the flights API, both of which return live fares. SWISS fares appear in your search results whenever our flight suppliers offer them for your route and dates. You fund a prepaid balance in advance and bookings are paid from it. Baggage, change and refund terms are shown with each fare before you confirm.
SWISS airline codes explained
SWISS uses the two-letter IATA airline code LX and the three-letter ICAO code SWR. The IATA code LX is the one shown on tickets, fare displays and booking screens, while the ICAO code SWR is used in air traffic control and flight planning.
SWISS is a full-service carrier, based in Switzerland, operating mainly from Zurich (ZRH). It is a member of Star Alliance.
Booking SWISS fares as a travel agent
Travel agents book SWISS fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live LX fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. SWISS results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
Search SWISS (LX) through the flights API
Developers and agencies can run the same SWISS search from their own site, app or back office through the IATA.co flights API. Filter a search by the carrier code LX and read the fares back as JSON, then book from the same prepaid balance. See the flights API and the API docs for the full reference.
