Running into a similar issue. Searching for LAX-TYO-MNL for March 7 on JL, AA site shows inventory (in first) that I can't book. Interestingly, Alaska shows much of the same inventory (and a little more) but in business, not first. Have tried chat and both the USA and Australian call centers and they see zero business availability that day. Any other tricks I can try to get this booked? Unfortunately I don't have Alaska miles to burn. Thanks!
