I just went on BA's site and it shows it's still available! However, Alaska's site is still not showing it properly and it disappears when not in 'award calendar' mode. Same thing happens when I checked SFO-HND on that date so maybe it's still too early to book... I just cross-checked BA's site with Alaska's site and Alaska's JL availability in all classes disappears starting Monday 9/24 (even though BA shows space). So my hunch is that in three days 9/26 will finally open up to book on Alaska since it seems they are a few days behind. *crosses fingers*
