Wait, this happened in the US?

Damn. I wouldn't be surprised about JL having issues in Japan. I figured they'd be more willing to help in the United States.

Let us know how this goes. Yes, JL should have reaccommodated you. JL does not like touching tickets at all if issued by AS. I tried going standby OKA-HND earlier this year. Even as a OW Emerald and Sapphire, no go. We were on a J award with plenty of space (unrelated issue, and yes they followed rules. This was just an example of JL being inflexible, that's it).
