This is a solid option for families planning a spring trip to Australia. Premium Economy offers a meaningful upgrade over coach on this 15-hour flight, with extra legroom, better recline, and improved meal service—helpful when traveling with kids or anyone who needs a bit more space.
The typical award rate for Premium Economy on this route runs around 80,000 United miles, so 70,000 miles represents a 13% savings. Not a massive discount, but worthwhile if you already have United miles sitting in your account and Sydney is on your list.
Availability shows only 5 seats remaining on the April 24, 2026 departure. If you're booking for a family of four or more, you may need to get creative with separate reservations or consider nearby dates.
One practical tip: check the United app as well as the website. Sometimes award inventory displays differently across platforms, and you may spot additional dates worth considering.
