Heathrow Airport issues message to all passengers with flights booked

Heathrow Airport is urging people to double-check a few essentials before arriving. Posting on X (formerly Twitter), Heathrow reminded passengers: "Travelling soon? Here's what to check before heading to the airport."

It’s clear that the airport is a bustling hub, so staying alert and prepared is key to ensuring a smooth journey. In their 2024 annual report , they highlighted the sheer scale of their operations, noting that they welcomed an impressive 83.9 million passengers last year.

In a check list of the five things you need to do, they said you need to ensure you have done the following before setting off:

• Check in online or via your airline's app
• Have your passport/ID ready
• Bring your flight booking confirmation
• Bring any travel documents your destination may need
• Remember 100ml rule for security check

When it comes to liquids, the airport confirmed on their hand baggage and liquids section that "only limited quantities of liquids may be carried through airport security into the departure lounge. This includes bottled drinks, suntan lotion, fragrances, cosmetics, toiletries and all frozen liquids."

The following restrictions apply to all liquids, creams, gels, pastes and aerosols taken through security control:

• Liquids may only be carried in containers holding 100ml or less.
• They must be carried separately in a single bag which is:
  • Transparent and resealable
  • No larger than 20cm x 20cm (8in x 8in)
  • Able to close properly with all the items inside.
• At security control, place the bag in the tray with your other items.
• Liquids in containers over 100ml will not be permitted through security – please pack them in your hold baggage instead.

The following exceptions may be made to the 100ml rule:

• Liquid medicines: you are only permitted to carry quantities of liquid medication in excess of your personal liquid allowance where it is needed during the course of your flight. All medication should be accompanied by documentary proof of authenticity, such as a prescription or letter from a medical practitioner confirming that you need them for your journey. Liquid medication that is not required on the flight should be carried as hold luggage. Find out more about travelling with medicines.

• Baby food or baby milk: breast milk can be carried in the cabin when it is stored in a clear, transparent container or bag. Flasks cannot be permitted. The volume of each container / bag should not exceed 2 litres. Breast milk should be in a liquid format and not frozen. When travelling without an infant only breast milk can be carried in quantities greater than 100ml - this does not apply to formula milk or other baby juice / food. The airport asks passengers to check with your airline as individual hand baggage allowance can vary.

Explosive or flammable liquids, and those that are considered toxic, are not permitted in either hand or hold luggage. And if you're wondering when to arrive, Heathrow Airport recommends arriving three hours before an international flight. However if you're flying domestic, arrive two hours beforehand.
