It must be full on that particular day. I flown AK on BKI-LBU route before.
And the load is above the par. Perhaps i tried on April, it is available at RM29 one-way.
I hope AK will consider starting up Ipoh. The city have almost (or more) 1 million population and 70% are Chinease.
A powerful marketing strategy to any China routes will attract them.
And this might not happen in KUA.
Wutever it is, IPH must be extend or new aiport must be build.
