Hi, I have a somewhat different situation. I'm flying a business award ticket to NRT (using aa miles, but the plane is JAL), then leaving for DFW on a paid economy 6 hrs later (same day, with AA). my question is, will I be able to use any lounge? I don't have any elite status at the moment. I dont mind purchasing the one day pass for admirals club, but would much prefer access to sakura lounge.

Thanks,
Chip
