Hi Pratiksha, Yes, you can definitely go to Kuala Lumpur International Airport (KLIA) 12 hours before your flight! KLIA operates 24/7 so you can stay there overnight. Here are some things to consider: Check-in counters typically open 3 hours before departure for international flights. So while you can stay at the airport 12 hours early, you won't be able to check in that much sooner. There are plenty of amenities at KLIA to keep you occupied overnight, including restaurants, cafes, shops, and lounges. Some lounges are even open 24 hours. If you have a long layover, you can also consider paying for a day pass at a lounge for a more comfortable overnight stay. If you are on a tight budget, there are also some sleeping areas at KLIA that are free to use. These are located in the public areas of the terminals.
