Singapore Airlines: Hubs, Baggage, Check-In & Booking Guide

Singapore Airlines is Singapore's flag carrier and a member of Star Alliance. It's widely regarded as one of the world's leading airlines for service quality, operating a substantial long-haul network connecting Asia, Europe, Oceania, and the Americas.

Singapore Airlines operates from a single hub, Singapore Changi Airport (SIN), consistently ranked among the world's best airports and a major connecting point for Southeast Asia and beyond.

Singapore Airlines serves destinations across Asia, Europe, Oceania, and the Americas, including some of the longest scheduled nonstop flights in the world, both directly and through Star Alliance partners.

Baggage allowances vary by cabin class and fare type, with Singapore Airlines generally offering competitive allowances, particularly in Business and First/Suites classes. Confirm the current allowance for your specific fare before flying.

Check-in is available online, through the Singapore Airlines app, at airport kiosks, or at the counter. Online check-in typically opens 48 hours before departure.

Singapore Airlines offers Economy, Premium Economy, Business, and First Class/Suites (on select aircraft), with its Suites product known for private cabins on select long-haul routes.

For bookings that include a U.S. departure, the 24-hour free cancellation window under U.S. DOT rules typically applies for bookings made at least 7 days ahead. Beyond that, change and cancellation terms depend on the specific fare purchased.
