At the end of the current Japan Airlines schedule first class awards are wide open for two passengers on the New York JFK – Tokyo Haneda route.
You cannot yet book this space using American Airlines AAdvantage miles. Their booking calendar doesn’t extend past 331 days into the future. You can book these seats using miles in other oneworld frequent flyer programs, however.
For instance you can redeem British Airways Avios now for these flights. However BA’s pricing for long haul first class is exceptionally high at 140,000 miles each way. Fuel surcharges, though, are just $3.20 each way.
If award space remains available when the American AAdvantage booking window opens, you can spend 80,000 miles each way for JAL first class between the U.S. and Tokyo or 110,000 miles each way connecting onward in most of Asia.
