How do you survive an overnight layover at KLIA?

My overnight kit is always the same: eye mask, earplugs, toothbrush, charger, backup snack, and one layer that makes bad air-conditioning less miserable.

If easy budget-premium mix is real at KUL, I would build the whole stop around rest quality first and food second.

The biggest overnight mistake is pretending you can improvise sleep once you land. Pick the rest plan before the first flight even departs.

Even a mediocre hotel or sleep pod can be worth it if the next day in Kuala Lumpur matters at all.
