First off, welcome to FT. I think, though your idea is pretty good, that this won't work. After a few people post their award uses, others will go off-topic and start talking about how to maximize value. That just happens with an open forum, and has happened in the 100s of threads on this subject that we've had in the past. Also, many here use miles for tickets they would never consider buying with cash. I used AA miles for a CX F ticket to Hong Kong and Australia in 2001. The ticket on the CX website was over $20,000. Now, I wasn't about to pay $20,000 for an F ticket, but I also wouldn't have paid whatever the cheapest Y fare was. Had I not had miles, I simply would not have taken the trip. So how do you put a value on that ticket?
I think that there's enough info out there in the other threads on this subject for someone to find out how different folks value miles. And since there are so many different ways to value miles, it will be impossible to determine a standard value for a mile.
But, good luck to you.
