Its KrisConnect programme, expanded from April 2020, delivers NDC content and SIA APIs through the three GDSs, aggregators and technology partners including Travelfusion, TravelNDC and Verteil.

History of Singapore Airlines

Singapore Airlines traces its roots to Malayan Airways, whose first scheduled service flew from Singapore's Kallang Airport to Kuala Lumpur, Ipoh and Penang on 1 May 1947. The airline became Malaysian Airways in 1963 and Malaysia-Singapore Airlines in 1966. In 1972 that joint carrier split into Malaysian Airline System and Singapore Airlines.

SIA joined Star Alliance in April 2000. On 15 October 2007 it took delivery of the world's first Airbus A380, flying its first A380 service, from Singapore to Sydney, on 25 October. It later launched the Airbus A350-900ULR and the Boeing 787-10 in 2018. The regional subsidiary SilkAir, originally Tradewinds, was folded into the main airline, which brought Boeing 737s back into the mainline fleet from 2021.

The group also runs Scoot, a wholly owned low-cost airline flying since 2012. In November 2024 SIA's joint venture with Tata, Vistara, merged into Air India, and SIA became a 25.1% shareholder in the enlarged Air India group.
