You can buy at any of the licensed duty free shops but you need to provide your ic number and they will key it into the system. With one ic you can buy 5 litres per month and enjoy it in the island but you can only bring 1 liter out of Langkawi. That too only 48 hours after arriving in Langkawi.

And you can bring it in your hand carry luggage too. Most of the people who buy alcohol at the airport do so. But if I were you I wouldn't spend my money at the airport duty free shop, as everything there is expensive. You will save more at the shops in Kuah. The duty free shop in Cenang Mall is also quite cheap.
