Singapore Airlines and Air China are both full-service flag carriers and both members of Star Alliance. Travellers compare them mainly for trips between Singapore and China, and for journeys to Asia that connect through Changi or Beijing.
Quick verdict
Both are full-service airlines, so the choice comes down to network and product. Singapore Airlines suits travellers who want a Singapore hub and a four-cabin product on its A380 aircraft. Air China suits those heading to or within China, where its 218 destinations and Beijing, Chengdu and Shanghai hubs give far more onward options. Check the aircraft on your specific flight, as cabins vary on both.
Choose Singapore Airlines if…
- You want to connect through Changi, its sole hub, to Southeast Asia, Australia or beyond.
- You want the option of a First (Suites) or Premium Economy cabin, available on its A380 and some 777-300ER aircraft.
- You value a modern fleet: 164 aircraft with 31 Boeing 777-9s on order for delivery from 2027.
Choose Air China if…
- Your trip ends in China, especially beyond Beijing or Shanghai, where its 218 destinations help with onward connections.
- You want to connect via Beijing Capital, Beijing Daxing, Chengdu or Shanghai Pudong.
- You want a larger airline with two free checked bags on many international Economy fares such as US–China, but confirm the allowance on your booking.
