About Singapore Airlines
Singapore Airlines is the flag carrier of Singapore and a member of Star Alliance. From its home at Changi Airport it flies to cities across Southeast Asia, North Asia, India, Australia and New Zealand, Europe, Africa and North America, which makes Singapore a common connecting point between Europe and the South West Pacific. The airline sells Suites and First Class on selected aircraft, along with Business Class, Premium Economy and Economy. Its low-cost sister airline, Scoot, belongs to the same group and shares the Changi hub.
On IATA.co you can search live Singapore Airlines fares in the booking portal, or request them through the flights API if you are building your own tool. Singapore Airlines fares appear in your search results whenever our flight suppliers offer them for your route and dates. Bookings are paid from your prepaid balance, and the fare rules are shown before you confirm, so you can check change and refund conditions for the exact fare you picked.

Booking Singapore Airlines fares as a travel agent
Travel agents book Singapore Airlines fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live SQ 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. Singapore Airlines 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.
