Air conditioning problem of Malaysia Airlines plane from Beijing to Kuala Lumpur ~

The temperature is around 20, which is still quite cold. Just wear a pair of jeans and a shirt. As long as it is not a low-cost airline, blankets are usually provided. If it's cold, you need one more.

However, you still have to wear long-sleeved coats and trousers when you go out, and there are many air conditioners in Kuala Lumpur airport.
