We are using a OW F award for ORD-NRT-BKK in August. Outbound is JL in J as neither JL or AA have award F at this point. I may actually have to choose between keeping my J on JL or jumping to AA F once it opens up--AA F seems likely to pop up at some point, but I doubt JL will (EF shows F4). I know comparing J to J or F to F on the 2 airlines was done on FT recently, but have not seen my issue come up.

Any thoughts on whether AA F trumps JL J? Just based on my poor experience with AA FAs in J to Europe and Asia, I think I am better off with JL, but it may be a closer call.
