As an example, I found seats departing SEA on Monday, November 11, and returning from NRT on Monday, November 18, 2019.
Fares at this price are available starting in late August through early December, with a few dates available for return flights toward the end of December. Departures are valid on Monday through Thursdays. A 7-day minimum stay is required.
Fares include standard carry-on baggage and two pieces of checked luggage.
You may choose your own assignments from standard economy class seats that are still available at no extra charge.
This fare can be purchased via the American Airlines website for a few dollars less than what is offered on JAL's site. This is an amazing deal considering Delta and ANA are charging hundreds more for the same nonstop city-to-city pair.
