The first time we flew with diabetes devices (pump and/or CGM), we packed like we were moving countries and still worried about the checkpoint. Spoiler: diabetes supplies are allowed through TSA. The hard part is not “is insulin legal on a plane” – it is knowing what to say, what to keep in carry-on, and how to handle scanners without wrecking a device. Here is the parent playbook we use now.

Not medical or legal advice. TSA policy and device manufacturer guidance can change. Always check current TSA insulin pump and glucose monitor rules and your pump/CGM maker’s travel page before you fly.
Once you land, the park itself is its own puzzle. We put the ride, heat, and disability access side of it in theme parks and Disney with Type 1.
The short answer
- Yes – insulin, pumps, CGMs, meters, juice, gels, and diabetes supplies can go through security when screened.
- Tell the officer early – “We have type 1 diabetes supplies” (and name any worn medical device) before the bin chaos starts.
- Carry-on only for the important stuff – never check insulin, spare pumps/sensors, or emergency glucagon if you can help it. Bags get lost.
- Devices: follow your manufacturer’s guidance on metal detectors, body scanners, and X-ray. When in doubt, ask for a pat-down and hand inspection.
What TSA actually says
Per TSA’s public guidance on insulin pumps and glucose monitors (updated regularly on tsa.gov):
- Carry-on: yes (with special instructions)
- Checked bags: yes for many items – but we still keep critical meds and devices with us
- Notify the TSA officer that you have diabetes and are carrying supplies
- Insulin pumps and supplies should be accompanied by insulin; insulin should be clearly identified
- You can ask for a Passenger Support Specialist or Supervisory TSA Officer if you need help
- Devices with lithium batteries should generally travel in carry-on
The ADA also summarizes that diabetes equipment, medications, and related liquids/gels are allowed through the checkpoint once properly screened. The final call at the lane is still the officer’s – calm, clear, and prepared beats arguing from memory.
What we say at the checkpoint
Before shoes and laptops:
“Hi – my child has type 1 diabetes. We have insulin, a pump/CGM, and medical liquids. We need to keep devices with us / request alternative screening per manufacturer guidance.”
Optional helpers:
- TSA disability / medical notification card (download from TSA if you want something to hand over)
- A printed or phone copy of the prescription or a clinic letter (not always required, sometimes speeds things up)
- Manufacturer airport card if your pump company provides one
Metal detector vs body scanner vs X-ray
This is where parents get the most conflicting advice – because TSA allows the devices, while manufacturers often warn about body scanners and X-ray for electronics.
Patterns we follow (always confirm for your exact model):
- Metal detector: many families walk through wearing pump and CGM without issues.
- Body scanner (AIT / millimeter wave): several pump and CGM makers recommend avoiding body scanners with the device on. You can usually request a pat-down instead.
- X-ray belt: do not assume “just put the pump in the bin” is fine. Some people detach a tubed pump; many manufacturers say not to X-ray the device. Ask for hand inspection of the medical device.
- Spare sensors, pods, transmitters in packaging: often fine in carry-on; still tell the officer if the bin looks like a mystery electronics pile.
If an officer seems unsure, politely ask for a supervisor. We are not trying to skip security – we are trying to screen correctly without frying a $1000 device.
What goes in the personal-item bag (not the checked suitcase)
Full packing lists live in our T1D travel packing checklist. For the airport day specifically, the “do not check” pile is:
- Insulin (extra for delays – more than you think you need)
- Pump + spare pods/infusion sets / cartridges
- CGM sensors + transmitter if separate
- Meter, strips, lancets (even if you “never” use fingersticks anymore)
- Fast carbs: juice boxes, gels, and glucose tabs (we buy the multi-pack)
- Glucagon / emergency meds as prescribed
- Chargers, a small USB power bank, phone with CGM app
- A Frio cooling wallet (or similar) if your trip has heat – see also insulin storage notes on the site
We keep airport-day supplies in a labeled clear pouch so TSA can see it is medical, not mystery electronics. A simple clear TSA-style bag or a dedicated diabetes supply organizer both work – pull one bag for inspection instead of unpacking the whole backpack on a folding table.
Juice, gels, and the 3-1-1 myth
Diabetes liquids and gels for medical use are not the same as random shampoo. Declare them. Keep them accessible. We still pack more solid carbs than we think we need – glucose tabs and packaged snacks – so we are not fully dependent on liquid screening mood that day.
Flying with a kid who has T1D
- Practice the script with your kid if they are old enough – “I have diabetes, this is my pump.” A kids medical ID bracelet helps strangers understand the beeps if you are not right there.
- Lows in line: treat first, security second. Officers have seen medical needs before.
- Seat strategy: aisle helps for bathroom, water, and bag access. Tell the flight attendant you have diabetes supplies if you want a heads-up for juice later.
- Time zones: plan basal / schedule changes with your care team before you leave, not at the gate.
- Plane food is not a plan. Bring backups. Delays happen.
Day-of airport checklist
- Insulin + devices in carry-on (double-check before you leave the house)
- Extra low snacks in the personal item, not buried under souvenirs
- Phone charged, CGM app working, offline music optional, glucose history not optional
- At the lane: announce diabetes / medical devices first
- Request pat-down / hand inspection if manufacturer says skip body scanner or X-ray
- After security: confirm pump/CGM still connected before you celebrate with airport pretzels

Bottom line
You can fly with type 1. Pack critical supplies in carry-on, tell TSA early, and screen devices the way the manufacturer recommends – even if that means a pat-down instead of the body scanner. The first trip is the scariest. The second trip you will mostly worry about whether the gate snacks are edible.
Parent experience only – confirm TSA and device rules for your trip dates, and ask your diabetes care team about insulin dosing across time zones.
