Hi all, I am wanting to redeem a one-way economy ticket on either a) KIX-PVG JL897 on 9/4 or 10/4, or b) NRT-PVG JL877 on 10/4. If this is posted in the wrong place, moderators please feel free to move to the appropriate forum.

I have the following redemption options and I'm looking for input on which would be the best value. None of the miles are expiring in the near future except for QR, where I have a small total balance of almost 26k out of which 10k are expiring on 31/12.

QR: 15k + unknown amount for fees and taxes (emailed but no response from QR, does anyone know?)

AA: 20k + 57 USD

Flying Blue: 15k + 603 RMB

BA Avios (borrowing from a friend): 7.5k + 59 GBP

In a small part, my decision would also be influenced by the difference, if any, in the catering, seating/aircraft used, and service. Sorry if this sounds lame for a short-haul economy flight, but I don't usually get to fly on JL, and having heard so many good things about Japanese airlines I'd like to maximise my experience.
