American Express Membership Rewards - Question: What airline should I use for NRT to MNL flight using MR points?

Hi Everyone, I need help on where to transfer my MR points to book a flight for my mom from NRT to MNL in March of 2013. I currently have 30K+ MR points. I checked on avios in which i only need 20K points for round trip but availability is close to none. Please help!

Question moved from MilesBuzz! to American Express forum because it pertains to Membership Rewards.

Delta and ANA (both MR transfer partners) serve this route as well. Might check price and availability with them.
