I have a flight to KL with Air Asia X coming up.

I have a flight to KL with Air Asia X coming up. I am in KL for 12 hours before I take a flight to LHR with Malaysian Airlines. I am looking at book an Airport Room during transit. Can someone tell me if this is possible as the room is on the airport side and Air Asia and Malaysian fly out of seperate terminals, I can only assume I can book a room if I stayed on the airport side only?

Yes, there are two airside hotels in KLIA (one in the main terminal and one the satalite terminal - I prefer the one in the satalite terminal). You should book these in advance.

After you arrive with AirAsia, proceed through immigration, collect your bags and go through customs. Then either get a taxi (should be around 20RM) or the bus (not sure on the price) over to KLIA. Check in with Malaysia and go through immigration and you will be able to access the hotel.

There are also a number of hotels (landside) around the airport, although in my opinion if you're just going to sleep the airside hotel offers the best value for money.

Once KLIA2 opens (where AirAsia will be moving to) you will be able to get the train to KLIA (where Malaysia operates) for 2RM.

If your AirAsia flight is before they move to KLIA2, the nearby Tune Hotel is a decent enough place to crash for 8 hours or so. However, if you're going to disembark your AirAsia X flight at KLIA2 (for flights from May 9th),

You may be able to check-in early to your MH flight (particularly if you are oneworld Sapphire/Emerald, use the business/first check-in counters and are travelling with carry-on luggage only), but I wouldn't rely on being able to do so.

There are hotels near to the airport which may offer a shuttle service, but it's probably easiest to catch the KLIA Express into KL Sentral and stay at the Hilton, Le Meridien or Aloft (which are right next to the station).

Thanks for the advice gents. I didn't think it was possible to check in with Malaysian at least 10 hours before my flight just so I can checkin to the hotel (airport side). Am I incorrect and infact can do this or do I just get a room on the land side and check in as per normal the next morning?

So I just read the airside hotel is for passengers who don't need to go through Immigration  therefore is only available for those who are transiting only. As AA and Malaysian don't share the same terminal I don't think it will be possible to stay on the airside.

It is not possible to stay airside, but Rakesh is correct with his summary. You will need to clear customs/immigration upon arrival and pick up your luggage at the LCC. Then transfer to KLIA. Malaysia Airlines does allow advance check in, so no problems arriving 10 hours early (unless its a codeshare not operated on their metal).

Then clear exit formalities at KLIA and head for the transit hotel at the satellite terminal, from which your London flight will also depart. The hotel will not care whether you have remained airside or not during your transfer and will gladly sell you a room if they have one available.

So it is possible then Trip88? I just received an email from Malaysian who advised check-in counters do not open until 3 hours before flight however I can web check in 24 hours before which means I can then drop my luggage off and head straight through Immigration (10 hours before), happy days!

Broderick, it appears that the mall in front of KLIA2 has hotel-style bedrooms at the Premium Plaza lounge (landside).
