Cheap flights from Perth to Miami (PER to MIA) from $1,643

The cheapest month to fly is October, and departing on Mondays typically offers the best fares.

Book at the right time: For international flights, aim to book 6–10 weeks ahead. Last-minute fares on Perth to Miami are rarely cheap, and prices spike sharply within 2 weeks of departure.

Shift your dates by a day or two: Mondays are typically the cheapest day to fly this route. Avoiding Friday and Sunday departures can save significantly. October is historically the cheapest month on this route.

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. ANA and Air Canada 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.

Compare two one-ways against a return: On some international routes, booking a one-way with one airline and the return with another can undercut a standard return ticket — especially if a budget carrier covers one direction. Check both options with the flexible dates calendar above.
