Heathrow urges travellers to stay updated and comply with new security rules amid pandemic travel advisories

Tuesday, 4 November 2025 5:09AM UTC

Heathrow Airport has issued crucial guidance for holidaymakers, emphasising the importance of checking latest government travel advice and adhering to hand luggage regulations to ensure smooth international journeys in the evolving travel landscape.

Heathrow Airport has issued an important advisory for travellers planning holidays abroad, urging them to stay informed and prepared by checking the latest government travel advice and registering for updates. The airport’s message, posted on X (formerly Twitter), advised prospective passengers to consult the Foreign, Commonwealth and Development Office (FCDO) travel guidance and sign up for email alerts via the official UK government website.

The FCDO plays a critical role in supporting UK citizens overseas by providing comprehensive travel information for 226 countries and territories. This includes details on current incidents, security situations, visa requirements, and other essential travel specifics. Alongside this, travellers are encouraged to use the TravelHealthPro service managed by the National Travel Health Network and Centre (NaTHNaC) for health-related updates, such as immunisation recommendations and disease outbreak alerts. Experts generally recommend reviewing health and vaccination advice at least eight weeks before departure.

A government travel checklist highlights key precautions holidaymakers should take, such as researching their destination, securing travel insurance as soon as a trip is booked, verifying necessary documents, and preparing contingency plans. The FCDO also operates a 24-hour helpline and encourages travellers to contact the nearest British embassy abroad if assistance is needed. The government cautions, however, that while the checklist aims to help ensure a trouble-free trip, no foreign travel can be guaranteed as completely safe, placing the onus on individuals to take personal responsibility.

Regarding security regulations for hand luggage, Heathrow Airport reiterates the longstanding UK government rules limiting liquids to containers of 100ml or less, which must be placed in a transparent, resealable plastic bag with a maximum capacity of one litre. Each passenger is allowed two items of hand baggage, with each bag’s dimensions not exceeding 56cm x 45cm x 25cm. Exceptions to liquid limits apply to essential medicines, baby food, and milk; these items can exceed 100ml but must undergo additional screening. Prohibited items include sharp objects, firearms, and flammable substances.

Passengers are advised to check the specific liquid restrictions not only at Heathrow but also at any connecting airports and for their return journey, as local rules can vary. Some airports have begun employing advanced CT scanners that allow passengers to keep liquids and electronics inside bags without removal, with certain airports raising the liquid limit up to two litres. However, Heathrow has not yet implemented these newer measures and continues to enforce the 100ml liquid rule with items housed in a single clear bag.

The government also clarifies what constitutes a liquid in hand luggage, encompassing sprays, pastes, gels, drinks, cosmetics, and semi-liquid foods such as jams and syrups. Travellers should also consult airlines for rules regarding controlled substances or items like needles and medical equipment.

In sum, Heathrow’s recent alert serves as a timely reminder for travellers to ensure thorough preparation, including verification of up-to-date travel advisories and compliance with hand luggage restrictions, to help smooth their journey and avoid potential delays or complications.
