Can diabetics travel by plane?
Yes, absolutely! People with diabetes travel by air every day. With a bit of planning and awareness, you can fly safely and comfortably. Here are a few things to consider before your next flight:
- Before you fly: If it's been a while since your last trip or if you're embarking on a longer flight than usual, consider booking a consultation with your GP or diabetes nurse. They can help you adjust your medication schedule and offer guidance on what to pack.
- Medical documentation: Carry a letter from your doctor outlining your condition, the medications you take, and any medical devices you use. While documentation is not required for flying within the UK, having this on hand can help in case you encounter questions from airline staff or security personnel.
- Travel insurance: Make sure your travel insurance covers diabetes-related care while abroad. It's always better to be prepared in case of an emergency!

Can you bring all your diabetes supplies on the plane?
You're allowed to bring your diabetes supplies on the plane, but there are a few key points to keep in mind:
- Carry-on over checked luggage: Always keep insulin and other diabetes medications, glucose meters, lancets, and any other supplies in your hand luggage. Checked bags can be subject to extreme temperatures and handling delays.
- Liquid injectable diabetes medications, including insulin, Ozempic, Victoza, Trulicity, or others are permitted through airport security screenings. If flying with less than 100 ml within the UK, you do not need documentation.
- Used needles necessary for injections must be carried in sharps bins or similar hard-surface containers. Unused needles are allowed if accompanied by medication.
- A Diabetes Travel Letter or a medical certificate can smooth the process at airport security. While not required when flying within the UK, it can be helpful when passing through customs after international flights.

What if you use an insulin pump or CGM?
Before the screening process, let airport personnel know that you wear an insulin pump or CGM and ask for a visual inspection if needed. Some devices may be sensitive to certain types of airport scanners, especially x-ray machines and full body scanners. Your pump manufacturer or diabetes care team can advise you on the best approach.

Does flying affect blood sugar?
Flying can influence blood sugar levels in a number of ways, so it's important to be prepared and know what to expect:
- Cabin pressure and blood sugar: Changes in cabin pressure and altitude can sometimes cause fluctuations in blood sugar levels. This makes frequent blood glucose checks essential.
- Meal timing and insulin dosing: Long flights that cross multiple time zones may disrupt your normal eating schedule. You might need to adjust the timing of your insulin or oral medications. Your diabetes care provider can help you plan this in advance.
- Staying hydrated: The dry air in airplanes can lead to dehydration, which may affect blood sugar control. Drink plenty of water throughout the flight.
- In-flight snacks and beverages: Stick to healthy snacks and monitor your intake of sugary or high-carb items. If you need a quick boost for low blood sugar, keep glucose tablets or gels within reach.
- Staying active: When possible, walk up and down the aisle periodically to help circulation and prevent insulin absorption from slowing down, especially during long-haul flights.
Are there diabetic meals on planes?
Yes, fortunately, many airlines offer diabetic-friendly meal options. British Airways, for instance, offers diabetic meal options with minimal sugar content. However, it's important to plan ahead and arrange these in advance.
- Requesting a special meal: When booking your ticket or shortly after, contact the airline to request a diabetic meal. These meals typically contain fewer carbohydrates and a more balanced mix of protein and fibre.
- Checking meal contents: Even diabetic meals may not perfectly match your nutrition needs. Be ready to check your blood sugar and make adjustments if the meal contains more or fewer carbs than expected.
- Bringing your own food: For peace of mind, pack snacks or small meals that you know work for you. High-protein snacks, nuts, or pre-measured portions of your go-to food can be lifesavers if airline meals don't meet your needs.
Can diabetics board planes early?
While it isn't a universal policy, some airlines allow passengers with medical needs to board early.
Boarding early can give you time to organise your seating area, ensure your diabetes supplies are easily accessible, and get comfortable before the rush.
- How to request early boarding: Contact the airline in advance or let the gate agent know about your condition. In many cases, a polite request accompanied by your doctor's letter is enough.
- Other considerations: Informing the cabin crew about your diabetes isn't mandatory, but doing so can be helpful. They can provide support if you experience any issues during the flight.
Frequently Asked Questions About Flying with Diabetes

Can I carry snacks or glucose tablets through airport security?

Should I tell the airline I have diabetes?
You don't have to disclose your diabetes to the airline, but letting them know can be helpful if you require special meals, early boarding, or assistance during the flight. Some airlines even have policies to accommodate passengers with medical conditions.

Delays and cancellations can disrupt meal and medication schedules. If this happens, test your blood sugar more frequently and adjust your insulin or oral medications as needed. Make sure you have enough supplies on hand to last longer than the expected travel time.
How do I handle high blood sugar while flying?
If your blood sugar runs high during a flight, stay calm and drink plenty of water. Test frequently, and if necessary, take a corrective dose of insulin based on your doctor's guidelines. Avoid consuming sugary snacks or drinks unless your blood sugar drops.
What should I do if I have motion sickness?
If you have motion sickness, it can be harder to eat or drink normally, which might affect blood sugar levels. Carry ginger-based snacks or ask the flight crew for motion sickness remedies. Test your blood sugar often, and consider adjusting your insulin if you're unable to eat.
If you start feeling unwell, inform the cabin crew immediately. They can provide assistance and help you access your medical supplies. Don't hesitate to test your blood sugar if you suspect a hypo or hyperglycemic episode.
Can I get emergency medical help on the plane?
Most airlines have trained crew members who can assist in medical emergencies. If you need immediate help, alert the cabin crew. They may have first aid supplies, and in serious cases, they can contact a medical professional on the ground or divert the flight if necessary.
Flying with diabetes may require a bit more preparation, but it doesn't have to be stressful. By planning ahead, staying organised, and working closely with your healthcare provider, you can enjoy your flight and focus on the adventure that awaits. Remember, many people with diabetes travel by air regularly-and you can, too. Bon voyage!
