Alcohol in cabin baggage: security, airline and customs rules

Before packing alcohol, check five separate questions: strength, cabin screening, any transfer screening, your baggage allowance and destination customs. Passing one check does not settle the others. A miniature bottle, a sealed duty-free purchase and a bottle in checked baggage take different paths through these rules.

Cabin screening: check the container

For EU departures, ordinary cabin liquids use containers of no more than 100 ml inside a transparent bag of up to 1 litre. TSA screening in the US also limits ordinary containers to 100 ml, but uses a quart-sized bag. A partly empty 750 ml bottle is still a 750 ml container. Small bottles must also meet the alcohol-strength rules.

Alcohol strength: the FAA rule for US travel

The FAA distinguishes alcohol by volume (ABV). These are US dangerous-goods conditions, not a worldwide customs allowance. Check your operating airline and every country on the itinerary.

Duty-free and another security check

For EU screening, duty-free liquids and the receipt must remain sealed in the security bag provided at purchase. If an officer opens it, mention any onward connection so it can be resealed in a new security bag. Do not open it yourself before the final destination.

For an international arrival connecting within the US, TSA allows duty-free liquids over 100 ml when bought internationally, retailer-sealed in a transparent tamper-evident bag, and accompanied by the original receipt from a purchase within 48 hours. They must still pass screening. A shopping bag or an old reused security bag is insufficient.

Customs and the airline are separate checks

Check destination customs before buying: tax-free sale does not grant tax-free import, remove age restrictions or override import bans. EU guidance for entry from outside the EU distinguishes still wine and beer from the alternative spirits or fortified/sparkling-wine allowance. Travel within the EU for personal use has a different framework.

The airline sets baggage size, weight and item count; a duty-free purchase is not automatically an extra free bag. On flights covered by FAA rules, passengers may drink alcohol only when served by the airline. Crew are not obliged to serve a passenger’s own bottle.
