I am flying ORD-AMM-ORD on an L fare - Economy Semi Restricted .

I would appreciate your help in verification of earnings rate for award miles.

The trip is 12,472 mi RT per gcmap, and the earnings table on RJ states 115% earnings, so I will earn 14,260 RJ Miles?

I am also AA Platinum, and the earnings rate as PLAT on RJ for an L fare is 80%? Based on distance, not fare paid? so I would earn 9,977 AA awards miles (RDM)???

If my math is right, now I have to chose who to credit it to?

I earn more on RJ, but I am not familiar with the program (Just signed up, don't plan to fly more). More miles is better, but maybe not If I can't easily redeem (most likely on partner AA)

or should I just be safe and credit to AA (I have plenty of miles and will fly more soon, so would be nice to top off accoiunt)

I will try to ask for a RJ Challenge via email, if it is granted, it may convince me to go for RJ Sapphire to access OW lounges in US.

THANKS IN ADVANCE!
