Business Class and First Class usually include an even more generous checked baggage allowance.

Exact entitlements depend on your ticket type and KrisFlyer status, so please check your booking for full details.

Wi-Fi is available on most Singapore Airlines flights from Seattle to Australia once the aircraft reaches above 10,000 feet.

Non-members and additional users can purchase paid plans. The connection is suitable for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

Most journeys from Seattle to Australia connect through Singapore Changi Airport. For longer layovers, you can join the free Changi transit tour, subject to timing and eligibility, to see highlights of the city. For shorter stops, stay airside and make the most of Changi's gardens, walking trails, rest areas, shops, and dining options, or relax at a pay-per-use lounge or airport hotel within the terminals. Your time at the airport is more than just a wait — it is an integral part of your journey.

Time differences vary across Australia. Sydney, Melbourne, and Brisbane are typically 17 hours ahead of Seattle during their standard time and 19 hours ahead during their daylight saving time (roughly October to early April). Adelaide is usually 17.5 hours ahead, or 18.5 hours during its daylight saving period. Perth is generally 15 hours ahead of Seattle and does not observe daylight saving. Darwin is usually 16.5 hours ahead and also does not use daylight saving. Exact differences can vary when North American and Australian daylight saving dates do not align, so it is best to check close to your travel dates.

Yes, your baggage will typically be checked through to your final destination in Australia when flying via the layover airport on a single booking with Singapore Airlines, provided both flight segments are under the same booking reference (PNR), the connection is under 24 hours, and, for partner-operated onward flights, a through-check agreement is in place.

You may be able to plan a stopover at the layover city on your journey to Australia, subject to your ticket conditions and availability. When booking, you can search for multi-city options or speak with our customer service team or your travel agent, who can advise whether a stopover can be added to your itinerary.
