The bus delayed 20mins, no problem, but didn't feel good when you were going to airport and no ETA when it was delayed.
On time, bus driver did not speed
on time comfy BUT
i arrived at KLIA 2 and the bus boarded passengers for the return leg to Melaka
they sold my two seats
so boarding passengers were not happy i was sitting there
MAY I SUGGEST KLIA 1 then KLIA 2 less passengers tend to get off and on at KLIA1
so less chance of double booking seats.
