Lounge Access in CGK with Oneworld Emerald/AA Business Class
I'm EXP on AA and am flying economy from CGK-NRT on Japan Airlines, then business from NRT-DFW on AA. It appears there are only two lounges in CGK that are operated by third parties (JAS Premier Lounge, and Pura Indah Lounge). Can I access either of these lounges? If so, which one should I choose?
