On our flight to Japan, we booked using American Airline miles. If you want to book a one-way business class ticket to Japan, it’ll cost you 60,000 miles and $5.60. If you want to step it up a notch and fly first class, it’ll cost you 80,000 miles and $5.60. Do I think the extra 20,000 miles is worth it for first class? ABSOLUTELY. The difference in retail price would be about $6k to $10k….or you can book first class for only an additional 20,000 miles. In my opinion, it’s a no brainer—if you have the miles. And if you don’t have the extra miles, consider buying them. Our first leg was first class on American Airlines from Las Vegas to Chicago, then we flew Japan Airlines first class from Chicago to Tokyo, then our last leg (also on Japan Airlines) was in business class from Tokyo to Osaka. For the purposes of this post, I’ll be focusing on our first class experience on Japan Airlines from Chicago to Tokyo.
The flights were booked on American Airlines website and we were able to choose our seats on the AA segment, from LAS to ORD, on AA’s website. For seat selections on Japan airlines, we had to either call Japan Airlines directly or choose our seat assignments on their website.
