Why not fly NYC to either Bangkok/Hong Kong/Taipei using either JAL or Cathay Pacific via the Pacific? That is only 50K BA miles (return economy class) for a partner award. Don't mix JL and CX otherwise it is a lot more BA miles. Less time flying (and lower fuel fines by BA) Then use AA miles for 1-way trips (20K economy) within Asia. Or just use budget airlines in Thailand/Vietnam.
