If you've been waiting for a reasonable opportunity to book a Tokyo trip in Premium Economy using MileagePlus miles, this is a worthwhile option. The July 8, 2026 departure from SFO to NRT is currently pricing at 65,000 miles with minimal taxes, compared to the roughly 80,000 miles United typically charges for this cabin on transpacific routes.
Premium Economy on United's 777s and 787s offers a meaningful upgrade over standard economy: wider seats with more recline, enhanced meal service, and priority boarding. For a 10-plus hour flight to Japan, the extra comfort can make a real difference, especially if you're traveling with family.
Availability appears to be wide open right now, which is notable for summer travel to Japan. July falls during peak season, so finding any award space at below-average rates is worth acting on if your dates are flexible enough to make this work.
One practical consideration: if you don't have 65,000 miles in your account yet, United does allow you to combine miles with cash or transfer points from Chase Ultimate Rewards at a 1:1 ratio. Just make sure to transfer before searching, as award pricing can shift.
