I would like to redeem my asiamiles for a flight from Shanghai PVG to Seoul ICN.
Its 15,000 miles for China Eastern,

I went through the asiamiles website and had to fill out my details. It requires my credit card info before I can make a reservation/redemption request.

1) How do I found what the tax is going to be?
2) How long does it take to request for redemption ?

Thanks
