Have faith CMBurchhardt. Zuji is a responsible booking site here in Asia/Pacific, in fact it is a Travelocity company. From my limited experience with the AirAsia website, it is often busy. On those short interAsia flights, Air Asia is a much cheaper alternative to the likes of TG, SQ, MH etc. Generally on time but just grit your teeth and bear the flight stuffed in a sardine can. It can be chaos at the LCCT in KUL so allow plenty of time on your return flight. And remember the LCCT is on the other side of KLIA and a longer taxi ride from the city. Dont take the Express train from the city, it takes you to KLIA and not LCCT although there are coaches from the city somewhere to LCCT. I think that after this experience, you’ll be back to the mainline carriers.
