when you say SZB as alternate do you mean Scheduled? that being the case Sultan Ismail hit the nail on the head. I fly out of that place and there aint any decent way to get to KL compared to KLIA.
When I first arrived I had to commute from Near PD for a while and compared to The Big one SZB Sux, It'll cost the savings made to instigate a decent Link network.
Have a nice day,
