Founded in 1972, it is a member of Star Alliance and part of 新航集团.

This page gathers the essentials for flying with Singapore Airlines: official website, fares, online check-in, baggage rules and customer service contacts.

Singapore Airlines, established in 1972, sits within 新航集团; Star Alliance membership extends its reach through partner networks and unlocks reciprocal lounge, priority and mileage benefits.

In network terms, Singapore Airlines's core strength is Six continents via Changi. At Singapore Changi the airline runs its own check-in zones and premium facilities, and minimum connection times are most reliable there.

Booking tips: fares float with live inventory — 2–6 weeks out (2–4 months long-haul) is usually the trough, and member pricing can undercut platforms. Add your KrisFlyer number at booking; retro-crediting needs boarding passes. Paid upgrade windows open around check-in at prices well below purchase-time premiums, and pre-bought extra baggage saves 30%+ versus airport rates.
