There are large swaths of "availability" for 50k miles on JAL, premium economy, HND to DFW. Yet for every single date I select, I get this error. "Choose a different flight or fare. We're sorry but at least one of the flights or fares you chose is no longer available." This is for any of the dates April-June 2025 and in August 2025, as well.

Is there a trick to get around this? I've called in and talked to many agents and no one can help. I even had the web team I got transferred to hang up on me after being on hold for an hour. As an executive platinum member. Sheesh!

Any help is appreciated.
