This is a solid opportunity for families planning a summer trip to Australia. Premium Economy offers a meaningful upgrade over standard economy on the long transpacific crossing—extra legroom, better seats, and improved meal service make the 15-hour flight considerably more comfortable, especially with kids.
The typical award rate for Premium Economy between LAX and Sydney runs around 80,000 United miles, so this 70,000-mile pricing represents decent savings. You're looking at keeping 10,000 miles in your account while still flying in a comfortable cabin. Availability appears strong for June 21, 2026, with multiple seats showing.
One practical consideration: June falls during Australia's winter, so pack accordingly if you're heading to Sydney. It's also the start of ski season if you're considering a side trip to the Snowy Mountains.
If you're booking for a family, search for seats one at a time rather than all at once—award inventory sometimes shows more availability for single passengers than for groups.
