I believe that you can now check in months ahead even just after booking the flight, so try their web check in service.

But do check to see if you need to pas through immigration -I suspect you might a stheir Fly Thru service is only for selected routes.

Be aware. Last time I arrived at LCCT from Thailand it took just over an hour to get through immigration. A friend flew in from OZ yesterday and it took 1 hr 40 mins of queing to get through immigration.

In fact every time I have arrived at LCCT I have had to queue for a long time.

So I would suggest you need at least 2.5 hours between flights minimum.

Or look at MAS fares. They are often not that much more but in using KLIA main airport you will be able to use transit and avoid immigration.

Using LCCT for arriving international flights is most certainly a case of 'you get what you pay for'.
