Your time at the airport is more than just a wait - it is an integral part of your journey.

Seattle is in the Pacific Time Zone. Sydney, Melbourne, and Brisbane are generally 17 hours ahead of Seattle during the Northern Hemisphere winter, shifting to 19 hours ahead when Australian daylight saving is in effect and the United States is on daylight saving time. Perth is usually 15 or 16 hours ahead depending on seasonal changes, while Adelaide and Darwin sit between the east coast and Perth with offsets of roughly 16.5 to 18.5 hours ahead of Seattle across the year. Always check close to your travel dates, as both Australia and the United States observe daylight saving on different schedules.
