Travelers flying with AirAsia departing from KLIA2 do take note, AirAsia is enforcing the 7kg luggage limit for carry-on luggage. Which means, you are only allowed to bring a TOTAL of 7KG worth irregardless of how many bags you are carrying.
In my case, I have to think twice if I were to fly AirAsia as even my camera bag and computer bag combine would have exceeded 7KG and I don't trust the ground crew enough to check in the bags. So either I don't fly with AirAsia or I have to play properly on the best scenario to enable my gears to get into the plane with me without fear of it being damaged or stolen.
I was told that there's weighing machine at the departure lounge that all passengers have to go through to weight the luggage before they can board their flights. So if you are planning to fly with AirAsia, make sure you get to the airport at least 3 hours ahead of time. There's scenarios where friends have missed their flights because of what happened.
The ruling has been around for quite some time, the airline was quite relaxed until recently which caught a lot of flyers off guard and most of them vent their frustration social media.
Hopefully by the time you are flying in or flying out with AirAsia, they would have sorted out the issues and have a smooth transition for passengers (so you don't miss your flight).
