Airport security and diabetes technology

Many UK airports are now following guidance from the Civil Aviation Authority to help people with T1D get through airport security as quickly and easily as possible. The information below can help you make the process as smooth as possible.  

In June 2024, UK airports changed the devices they use to scan people and their carry-on luggage going through security. The advice can vary between devices, but most manufacturers of insulin pumps (standalone or as part of a hybrid closed loop (HCL) system) and continuous glucose monitors (CGM) advise that most technology should not pass through these new scanners, either through the full body scanners or on the carry-on luggage belt, as potential damage to the devices may occur.    

Information about preparing for your holiday can be found on the travelling section of our website. 

Airports can involve long walks between check-in, security and departure gates, so keep your hypo treatments somewhere easy to reach. 

Medical Device Awareness Card 

A Medical Device Awareness (MDA) Card was launched in the UK in 2019, sponsored by the UK Civil Aviation Authority (CAA) and Airport Operators Association (AOA).  

The card provides information about insulin pumps and CGMs for airport Security Officers and passengers, and aims to help make airport security easier for people living with T1D.

Simply print it off from the CAA website and take it to the airport with you.  

Going through Airport Security

What can go through the scanners and what can’t? 

Whether you use insulin pens, a CGM, an insulin pump or HCL system, you can safely take and use these on an aeroplane. 

Wearing a Sunflower Hidden Disability lanyard alerts the airport staff that you have a hidden disability or medical condition. Showing your MDA card as you get to the Security checkpoint makes the staff aware that you may require alternative security screening measures as you are wearing or carrying diabetes devices. 

Manufacturers of CGMs and insulin pumps have their own guidance on which devices can go through metal detectors, x-rays and full body scanners at airports. The advice can vary between devices. The latest guidance and statements issued by major insulin pump and CGM manufacturers gives information for each of their devices. Check the manufacturers’ websites or contact them for more information before you travel.   

Alternative security screening 

You can ask a security agent for an alternative method of screening, such as a pat-down and swab test. You should not be asked to remove your medical device. Showing your MDA Card can help make Security staff aware of the devices you may be wearing or carrying with you. If the only way through security is through one of the new scanners, you can request that they switch it off so that it doesn’t affect your technology.   

If you go through the security scanners while wearing your T1D devices, it may not be immediately obvious that the equipment has been affected. Always follow the manufacturer’s guidance to avoid any warranty issues or device malfunctions, 

What should you have in your hand luggage? 

You will need to take the equipment and supplies you need for your whole trip in your carry-on hand luggage. Most insulin pumps and CGMs should not be screened by the x-ray on the luggage belt, or by the body scanners so carry these with you to be manually checked.  

You’ll also need to carry anything that can’t be put in your hold luggage, like all your insulin, which can freeze in the hold. If you are using a cool bag, make sure it is a medically approved cool bag otherwise security staff may not accept them.   

You can take insulin pens through all the airport security scanners and detectors. Make sure you have your documents to hand in case you are asked about your insulin pen. Vials and cartridges of insulin, along with connected insulin pens – also known as smart pens – can go through the x-ray with the rest of your hand luggage. 

You may want to keep all your T1D supplies in a clear, separate bag in your hand luggage, so that you can take it out for manual security checks, with the rest of your luggage then going on the belt. This may help make the process quicker and easier. 

Contact the airport Assisted Travel service in advance 

Assisted Travel services can help make your journey through the airport easier, with support available from check-in through to boarding. Be prepared to share what support you might need including alternative security check due to your T1D devices like CGM or insulin pump.  

It’s best to request any assistance when you book your flight or holiday, or at least 48 hours before you travel. You can do this through your airline, travel agent or tour operator so they can make the right arrangements in advance. Some airports ask people to ‘check-in’ with their assisted travel service when you arrive at the airport. 

Some airlines allow passengers with health conditions to carry extra luggage for medical supplies. Contact your airline to see if they offer this and what documents they need to show that you have T1D.  

Sunflower (Hidden disability) lanyard 

AS T1D is legally classed as a hidden disability, many UK airports now provide hidden disability Sunflower lanyards for anyone with a hidden disability so that security staff are aware they may need extra help, understanding or knowledge.  

You should be able to get a sunflower lanyard at the airport’s Assisted Travel desk. You can contact the airport’s Assisted Travel service before you travel to make sure you can get one. 

If you have a severe hypo while at the airport, the airline may deem you unfit to fly due to medical concerns. Keep a closer eye on your blood glucose levels when in the airport and try and help prevent this, especially if there’s a long walk to the departure gate. 

You may also want to consider what documentation you will need to take with you when travelling.   

Take your time 

Allow at least one hour to go through security in case your luggage or T1D tech needs to be checked.  

Aeroplane food 

Contact your airline before you travel to make them aware of any dietary requirements you may have for the in-flight meal.
