There's a point at which the time spent boarding becomes too great considering the time in the air. The A380 is a large plane, and you really need 3 jetways to board it in any amount of reasonable time. The mentioned routes are mostly operated by 767s, 787s, 777s, or 330s. The 767 is the perfect plane for the route, and the 330 isn't half bad. TPE-HKG is another example of one of these super busy short routes.
