I am a Sri Lankan passport holder travelling from China to Sri Lanka with Air Asia. I have transit in Malaysia for 9 hours and 25 minutes. I need to know if I need a transit visa if I do not leave the airport.
As stated in Timatic, the database used by airlines:
Visa required, except for Holders of onward tickets for a max. transit time of 24 hours, arriving at and departing from Kuala Lumpur (KUL)
Visa required, except for Holders of a valid visa issued by Australia, China (People's Rep.), Chinese Taipei, Japan, Korea (Rep.), New Zealand or USA to nationals of Sri Lanka residing in country of nationality holding confirmed onward tickets for a max. transit For details, click here time of 120 hours, arriving at and departing from Kuala Lumpur (KUL) on Malaysia Airlines (MH) or Air Asia (AK). When transit time is longer than 8 hours it is permitted to leave the transit area
So no, you do not need a visa
