Right now, you can book economy class flights from Los Angeles (LAX) to Sydney (SYD) for 55,000 United MileagePlus miles plus $37 in taxes. We're seeing plenty of availability on April 13, 2026, which lands you in Australia during their autumn—a pleasant time to visit with mild weather and fewer crowds.
This rate comes in about 8% below the typical 60,000 miles United usually charges for this route in economy. While it's not the deepest discount we've seen, the combination of good availability and low taxes makes this a reasonable option if you've been planning a trip down under and have United miles to spend.
The April timing works well for families with school-age children who might be on spring break, though you'll want to check your specific district's calendar. Sydney in mid-April offers comfortable temperatures in the 60s and 70s (Fahrenheit), ideal for exploring the city and nearby Blue Mountains.
One practical tip: if you're booking for a family, search for your full party size right away. Award availability can vary by the number of seats, and what shows as available for one traveler may not be there for four.
