..... if not prepaid - thus if you had not paid for your baggage prior to arriving at the airport then you will incur a charge of $40 for up to 20kg as opposed to $16 if done online. Same applies to sporting equipment.
There is no charge for the actual check in for international passengers if the above does not apply.
From their website:
Will there be charges if I check in at the airport counter for my flight?
Check in fee of RM10 (it's equivalent in foreign currency) will be charged for all domestic flights in Malaysia at the counter and also to reprint boarding pass. There will be no counter check in fee for all international flights effective 22nd December 2011.
