This award pricing from LAX to NRT clocks in at roughly 8% below the typical 60,000-mile rate you'd normally see for this route in economy. It's not a blockbuster discount, but for families planning a spring break trip to Japan, the savings add up—especially when booking multiple seats.
Availability looks strong for April 17, 2026, with plenty of seats showing in the search results. That's encouraging news if you're trying to book three or four tickets together, which can often be a challenge on popular transpacific routes.
April is a particularly good time to visit Japan, as it falls during cherry blossom season in many regions. Booking this far out gives you time to plan around the blooms and lock in hotels before peak-season prices climb.
One practical note: if you don't have quite enough miles in your MileagePlus account, United does allow you to purchase additional miles to top off a booking. Just run the numbers first to make sure buying miles still makes the redemption worthwhile compared to paying cash.
