Award availability for Premium Economy between LAX and Sydney is showing plenty of seats on July 9, 2026. At 70,000 MileagePlus miles plus $36 in taxes, this is a solid option for families planning a winter break trip to Australia during their summer season.

The typical rate for this route in Premium Economy through United runs around 80,000 miles, so you're saving roughly 10,000 miles per ticket here. For a family of four, that adds up to 40,000 miles back in your pocket for future trips.

Premium Economy on this ultra-long-haul flight offers wider seats, extra legroom, and enhanced meal service—a meaningful upgrade when you're in the air for 15 hours. It's a comfortable middle ground between Economy and Business Class, especially for travelers with kids.

One practical tip: July falls during school holidays for many families, and Australia's winter weather is mild in Sydney, making it a popular time to visit. If your dates are flexible, search a few days in either direction to confirm you're seeing the best availability.
