What Are the Rules on Duty-Free Liquids in Hand Luggage?

What Are the Rules on Duty-Free Liquids in Hand Luggage?

Upon passing through security, you’ll encounter an extensive selection of spirits and perfumes, often exceeding the 100ml limit.

As these goods are purchased within the secure departures area of the airport, Duty-Free liquids are not subject to the same restrictions as those you personally carry.

The quantity you’re permitted to purchase may vary depending on your destination country, so it’s advisable to verify beforehand if you intend to make a substantial purchase.

There are also regulations regarding transporting Duty-Free items onto your flight. Purchased items must be securely sealed in a designated security bag at the time of purchase, with the accompanying receipt sealed and visible within.

Furthermore, it’s prudent to confirm whether you can transport Duty-Free liquids between connecting flights. You may be required to undergo security screening again at your connecting airport, so it’s important to ascertain whether any specific transfer protocols are in place.

  • Essential medicines exceeding 100ml, including liquid dietary supplements and inhalers
  • Necessary medical equipment is crucial for your journey

Proof that the medication is prescribed to you, such as a doctor’s letter or prescription copy, is required if the medication is:

  • In liquid form and contained in a receptacle larger than 100ml

Proof is not necessary if the medication is either:

  • In tablet form
  • Liquid in a container sized 100ml or smaller

How Many Bags of Liquids Can I Take?

Most airports follow the 3-1-1 rule for carry-on luggage. According to this rule, each passenger is generally allowed to bring one quart-sized clear plastic bag that can hold containers of liquids, gels, and aerosols. The containers inside the bag must be 3.4 ounces (100 millilitress) or less in size.

You can usually fit multiple containers into this single quart-sized bag as long as they are small enough and can close properly. Keep in mind that each passenger is usually allowed only one such bag.

Exceptions may be made for items like baby formula, milk, and medications, which may be allowed in larger quantities and separate from the quart-sized bag. It is always recommended to check with the specific airline and airport security guidelines for the most accurate and up-to-date information regarding liquid restrictions before your flight.

Can I Take Food on Board the Flight in My Hand Luggage?

Yes, you are generally allowed to take food on board the flight in your hand luggage when flying from the UK. However, there are a few things to keep in mind:

  1. Liquids: If your food items contain liquids such as sauces, dressings, or soups, they must adhere to the liquids restrictions mentioned earlier (3.4 ounces or 100 millilitress per container, fitting within a quart-sized bag).
  2. Security Screening: Food items may need to go through the security screening process separately, just like other items in your carry-on baggage. It’s a good idea to pack them in a way that makes it easy for security personnel to inspect if necessary.
  3. Fresh or Perishable Foods: If you’re carrying fresh or perishable food items, consider their temperature requirements and the duration of the flight. It’s important to ensure that the food remains safe to consume throughout the journey.
  4. Customs Restrictions: If you are travelling internationally, be aware that some countries have restrictions on bringing certain food items across borders. It’s advisable to check the customs regulations for your destination country to avoid any issues upon arrival.


In conclusion, knowing the rules and regulations for carrying liquids on a plane is important to ensure a smooth and stress-free travel experience. By following these guidelines, you can save yourself from any potential headaches or delays at airport security.

Pack your liquids in appropriate-sized containers and properly store them in a clear plastic bag. Always check with your airline for any additional restrictions before packing for your trip. With this knowledge, you can confidently enjoy your travels without worrying about carrying too much liquid on board.
