You can bring up to five litres of alcohol with an alcohol volume between 24% and 70%. This can travel in your cabin bag if you purchased it in the airport duty-free shop, or you can pack in your checked baggage.
Drinks above 70% alcohol volume are not permitted on board our aircraft in either checked baggage or hand baggage.
