This award availability is on April 24, 2026, departing from LAX to Tokyo Narita. At 110,000 miles, you're saving roughly 30,000 miles compared to the typical 140,000-mile pricing we usually see for business class on this transpacific route. The $6 in taxes keeps out-of-pocket costs minimal.
Availability is limited to just 4 seats, which could work well for a family of four traveling together. That said, don't wait too long to book since award space to Japan tends to disappear quickly, especially for spring travel.
One practical tip: April is a lovely time to visit Japan, often coinciding with the tail end of cherry blossom season in some regions. If your dates are flexible by a day or two, it's worth searching nearby dates to see if additional space opens up.
