Shift your dates by a day or two: Tuesdays are typically the cheapest day to fly this route. Avoiding Friday and Sunday departures can save significantly. November is historically the cheapest month on this route.
Weigh up connecting flights: Connecting flights on San Francisco to Perth can be 20–40% cheaper than direct options. If you have time to spare, it's worth comparing.
Factor in baggage fees: Low-cost carriers on this route often advertise attractive base fares but charge separately for checked luggage. Always compare the all-in price — a $20 cheaper fare plus $50 baggage fee is no saving. SWISS and Qantas may have different inclusions, so check each airline's fare conditions.
Search in private browsing: Some booking sites use cookies to track repeat searches and may show higher prices after multiple lookups. Use an incognito or private window — or just use Booked AI, which pulls live prices without any tracking markup.
