I flew LAX–TPE–LAX on JX a few months ago and was really happy with their premium economy product (booked through the AS website). I’m planning another trip, but I can’t seem to find any premium economy fares on AS anymore—not just on JX, but on other partners too, no matter the dates. Has anyone else noticed this? Would it make sense to call and book over the phone, or do agents just see the same availability that’s online?
