Or do i need to transparent immigration as well as etiquette as well as pick up luggage..in which box can we still stay during a airside hotel. Don’t wanna go outward a airfield for a night..

If a flight involves an overnight stop, you need to retrieve your bags and clear customs and Immigration. Then recheck-in for the domestic flight. If the flight do not involve an overnight break,[i.e. involving MAS confirmed connecting flights departing on the same day] your baggage will be "check-through" and you clear immigration at the transit hall, then broad the domestic flight. You would have been given a boarding pass when you initially check-in at the start of your journey. However, there may be slight changes from time to time, so it is advisable to ask when you first check in.
