This isn't a deeply discounted sweet spot, but it's a reliable option worth knowing about. Aeroplan is releasing economy award space from LAX to Sydney for 49,700 miles plus $122 in taxes—right in line with their typical pricing for this route, which usually runs around 50,000 miles.
The real appeal here is the availability. With plenty of seats showing for April 28, 2026, this is a good opportunity for families who need to book multiple tickets on the same flight. April falls during Australia's autumn, offering pleasant weather and fewer crowds than the summer holiday season.
One practical note: Aeroplan miles transfer from a variety of credit card programs including American Express Membership Rewards, Capital One, and Chase Ultimate Rewards. If you're a bit short on miles, you can top up your balance through a transfer, though allow a day or two for points to post before booking.
