Yes, you can carry alcohol in your hold (checked) luggage when flying with Jet2, provided it is packed securely and does not exceed the legal limits for the destination you are traveling to. Alcohol with an ABV between 24% and 70% is limited to 5 liters per person by international safety regulations, while there is typically no limit for beer and wine in checked bags, other than your standard weight allowance. However, you are strictly prohibited from consuming your own alcohol during the flight; any alcohol purchased at the airport or brought on board must remain sealed. Jet2's cabin crew is authorized to confiscate any open containers. Additionally, you cannot pack any alcohol with an ABV of over 70% in either checked or hand luggage, as it is classified as a flammable hazardous material.
