💼 Cabin bag
Yes
Permitted as a medical device. Inform the security officer before screening. You may request a pat-down if concerned about scanner interference with your device.
✈️ Hold (checked)
Yes
Permitted. Carry-on is strongly recommended so the device remains accessible and is not subjected to the rough handling of checked baggage.
💡 Tip: Inform the security officer that you are wearing or carrying a medical device before screening begins. You can request a pat-down instead of going through the body scanner if you are concerned about scanner interference with your device — this is your right in most regions.
