Flying with Tandem t:slim X2: Airport Security (2026)
The t:slim X2 has the strictest airport rules of any major pump. Tandem's position is simple: keep the pump away from every form of X-ray, including body scanners. It sounds dramatic. The actual routine takes about a minute once you have done it.
I wear an Omnipod 5, so I don't do the t:slim checkpoint routine myself. What follows is Tandem's published guidance plus standard TSA procedure. No guesswork, no forum lore.
The whole thing boils down to a single decision you make before you join the line: stay connected and use the metal detector, or disconnect and take the alternate screening. Everything else flows from that choice.
Tell us your trip length and we will work out infusion sets, cartridges, insulin, and backups for your t:slim X2.
Build my packing list →What Tandem Says, Exactly
Tandem publishes a travel card meant to be shown to TSA officers. Its guidance:
- Walk-through metal detectors: safe. The pump is built to withstand common electromagnetic interference.
- X-ray machines of any kind, including full-body scanners and luggage screening machines: the pump should not be exposed. Full stop.
- Option one: disconnect at the infusion site and ask the officer for alternate screening of the pump.
- Option two: stay connected, tell the officer about the pump, and walk through a standard metal detector wearing it.
- The pump complies with FAA wireless transmission standards and is safe to use on commercial aircraft.
- Print Tandem's travel card before you fly. It is a one-page document that explains the pump to the officer. You can get it from Tandem's website. Handing an officer a printed card beats explaining a medical device from scratch.
The Checkpoint, Step by Step
Say you've chosen to disconnect. Here is the sequence:
- Travel card in hand before your turn comes.
- "I'm wearing a Tandem insulin pump, a medical device. I'll disconnect for alternate screening, please."
- Disconnect at the infusion site. The site itself stays on your body.
- Hand the pump to the officer. You'll get a pat-down around the site and an explosives trace test of your hands. This is standard TSA procedure for any attached medical device. It takes a few minutes.
- Reconnect on the other side. Confirm the pump is running before you walk away.
Prefer to stay connected? Then it's simpler: tell the officer about the pump and walk through the standard metal detector wearing it. Done.
t:slim Security Quick Reference
| Item | Metal detector | Body scanner | Baggage X-ray |
|---|---|---|---|
| t:slim X2 (worn) | ✓ Safe | ✗ Avoid | N/A, worn on body |
| t:slim X2 (disconnected) | Hand to officer for alternate screening | ✗ Never on the belt | |
| Spare infusion sets and cartridges | N/A | N/A | ✓ Safe |
| Insulin | Declare at the checkpoint | ✓ Screened by X-ray or hand inspection | |
| Dexcom G6 (if paired) | ✓ Safe | ✗ Avoid, per Dexcom's G6 rule | Spares go in a separate bag, no X-ray |
Paired with a Dexcom? Read This
Many t:slim X2 users run Control-IQ with a Dexcom G6. The two devices follow separate rules. The pump avoids all X-ray. The G6 avoids AIT body scanners specifically. Requesting one pat-down covers both devices at once, which makes it the simplest option for combo users.
Packing for t:slim Travel
Pump travel means packing the pump's whole ecosystem, plus a backup plan for the day the pump quits.
- Infusion sets: one per 2 to 3 days, plus two spares. Sites get irritated. Sets fail.
- Cartridges: enough to match your sets, plus one spare.
- Insulin: your normal supply with buffer.
- Backup insulin delivery: syringes or insulin pens. If the pump dies on day three of a ten-day trip, you still need insulin. Non-negotiable.
- Charging: the t:slim X2 charges over micro-USB. Pack the cable and a small power bank. A dead pump delivers nothing.
- Tandem's printed travel card, kept with your supplies.
Wearing It on the Plane
The pump stays on and keeps delivering for the whole flight. It is designed for cabin conditions and meets FAA standards. Keep it accessible rather than buried in the overhead bin, so a mid-flight bolus doesn't require an expedition.
t:slim Travel Checklist
- ☐ Infusion sets: trip days divided by 3, plus 2
- ☐ Cartridges to match, plus 1
- ☐ Insulin plus buffer
- ☐ Syringes or pens as pump-failure backup
- ☐ Micro-USB cable and power bank
- ☐ Printed Tandem travel card
- ☐ Decide before the line: stay connected (metal detector) or disconnect (alternate screening)
- ☐ Pump never on the X-ray belt, in any state
- ☐ Everything in your carry-on. Never in checked luggage
Frequently Asked Questions
Can the Tandem t:slim X2 go through the airport body scanner?
No. Tandem states the pump should not be exposed to any form of X-ray, including full-body scanners. Use the walk-through metal detector or request alternate screening instead.
Do I have to disconnect my t:slim X2 at airport security?
No. Tandem gives you the choice: disconnect at the infusion site and ask for alternate screening, or stay connected and walk through a standard metal detector wearing the pump.
Can spare t:slim supplies go through the baggage X-ray?
Yes. Infusion sets, cartridges, and insulin ride the X-ray belt normally. Only the pump itself avoids X-ray exposure.
What about a Dexcom G6 paired with the t:slim X2?
The two devices follow separate rules. The pump avoids all X-ray, and the Dexcom G6 avoids AIT body scanners per Dexcom's guidance. Requesting one pat-down covers both devices at once.
Can I wear the t:slim X2 on the plane?
Yes. The pump stays on and keeps delivering throughout the flight. It complies with FAA wireless transmission standards for in-flight use.
What should I pack for t:slim X2 travel?
Infusion sets, cartridges, insulin with buffer, syringes or pens as a pump-failure backup, a micro-USB cable and power bank for charging, and Tandem's printed travel card.
