Why Flying with Diabetes Is Easier Than Ever

Airports and airlines are becoming more accommodating. Here’s some good news if you’re traveling with diabetes:
- No stress about supplies: TSA allows carrying insulin, syringes, glucose tablets, and even liquids over 3.4 oz. Just pack your diabetes supplies in your carry-on, label them clearly, and you’re all set to fly worry-free.
- Keep your devices on: You can keep your insulin pump and CGM on during security checks and the flight. You do not need to remove or disconnect them. Inform the officer beforehand to avoid complications.
- Trained staff onboard: Flight crews are trained to handle medical emergencies, including diabetes-related ones. Most airlines also carry basic medical supplies, so help is always nearby if you need it.
Pre-Flight Prep: Get Ready the Right Way

Here’s your simple checklist before heading to the airport:
- Talk to your doctor: Share your travel plans with your doctor before your trip. If you're crossing time zones, ask about adjusting your insulin schedule.
- Pack smart: Keep all your medicines and testing supplies in your carry-on. Bring extra medicines just in case of delays or lost luggage.
- Label everything: You can keep your medicines in their original packaging. Also, carry the prescriptions from your doctor to avoid confusion during security checks.
- Doctor’s note: Carry a doctor’s note that explains your condition and lists your medications and devices. It will make security checks smoother and answer any questions that may come up.
- Know the local clinics: Note down the nearest hospital or pharmacy near where you’re staying, especially if you’re traveling internationally. This small information could play a major role in case of emergencies

TSA rules make flying with diabetes easier, but it’s still good to be prepared:
- Tell the officer: Inform the TSA officer about your medical condition before the screening begins.
- Show your documentation: A TSA Notification Card or a letter from your doctor can make the process much smoother.
- Don’t remove your pump or CGM: You can request a hand inspection instead of letting devices go through X-rays.
- Ask for privacy: If you’re not comfortable with public screening, you can ask for a private room.
- Call TSA Cares (72 hours before): TSA offers extra help for travelers with medical needs.

Once onboard, a few simple habits can keep you well:
- Arrive early: Try to avoid situations where you need to rush, whether at security or for boarding. Arrive at the airport at least 3 hours before departure to complete all the checks.
- Keep supplies close: Your medicines, snacks, and check-up meters should stay in proximity. It will be easier for you to bring them out of your carry-ons when needed.
- Hydrate often: Water helps in regulating sugar levels. It is best you avoid sugary drinks and drink water at regular intervals.
- Move around: Sitting idle for long hours can lead to Deep Vein Thrombosis (DVT) formation of blood clots in deep veins. While space on an aircraft may be limited, you can still walk along the aisle or do simple stretching exercises while seated.
- Snack smart: Pack nuts, fruit, granola bars, or peanut butter. In case meals are delayed or off-schedule, these will keep your sugar stable.

Trying new foods is part of the fun—but keep your health in mind:
- Choose balanced meals: Go for lean protein, veggies, fruits, and whole grains. Limit sugary or high-carb dishes.
- Identify your carbs: Check your meals for sugar intake. Sauces, breads, or desserts can spike your sugar in no time.
- Space out meals: Skipping meals or overeating at a buffet is not recommended. You can pre-check with your doctor for meal preferences.
Special Tips for Long Flights (Like from the US to India)
Special Tips for Long Flights (Like from the US to India)
Traveling from the U.S. to India? These tips will help:
- Adjust insulin timing: If you are crossing time zones, be aware that your schedule will change along with it. Set phone alarms or reminders accordingly.
- Request special meals: Check with airlines if diabetes-friendly meals are available in-flight. Book them in advance if available.
- Wear comfy shoes and socks: If you are on a flight that will last more than 10 hours, opt for comfy shoes and socks.
- Avoid injecting air into insulin vials: Cabin pressure can affect insulin vials. Be gentle when drawing insulin.
- Compression socks help: Compression socks reduce travel fatigue by improving blood flow and preventing blood clot issues such as Deep Vein Thrombosis (DVT) due to long hours of sitting.
After You Land: Stay On Track

Although your vacation doesn't mean to take a break from care, you can keep these pointers in mind:
- Test often: Testing helps you keep your sugar levels in check. The best method is to check before meals, before bed, and anytime you feel “off.”
- Watch your feet: People with diabetes heal more slowly than expected, so even small cuts require attention. If you walk a lot, check your feet daily for cuts, blisters, or swelling. Try to wear shoes at all times (inside or outside).
- Keep an eye on the weather: Hot weather will lead to dehydration, which directly affects blood sugar control. On the other hand, cold weather could raise blood sugar levels, as the body becomes less active and stress hormones increase.
- Talk to your travel buddy: If you are traveling along with someone or in a group, it's best to let them know your situation. You will have a reliable hand in case of emergencies.
