Travelers have found that booking a Sunday departure is the best way to save up to 69% on the cost of booking your flights compared to booking on days of the week where this route is of high demand.
When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 46 days in advance, which can save you up to 16% on flights from Billings to Sydney compared to booking the week you need them. Waiting 46 days out may not be for everyone, so we have options available for flights within the next two weeks, with the lowest price starting at $972. For sooner than that we have options available in the next 3 days from $1089.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, March can be a great choice for travel to Sydney. Flights to Sydney from Billings in March are about $1040 on average during March, but can be found for as low as $734.
