CPAP Machines and Medical Devices
Carried as free medical equipment. Batteries must meet lithium limits and devices need prior airline intimation for in-flight use.
CPAP machines, oxygen concentrators, and other assistive medical devices travel free as additional cabin equipment. Keep batteries within lithium limits, inform the airline 48 hours ahead if you plan to use them onboard, and carry supporting medical letters.
Key highlights
- Notify the airline 48 hours in advance through the special assistance desk.
- Obtain a doctor letter stating the need for the device.
- Check battery watt-hour rating and carry enough charged spares.
Airlines differentiate between assistive devices and regular baggage—CPAPs don’t count toward cabin weight so long as they’re used for medical reasons. Still, they must clear security like any other electronic: remove from bags, place in trays, and be ready for swabs.
In-flight use requires coordination. Airlines need to verify that your device is FAA/ICAO approved, that it fits seat power ratings, and that you have enough battery to last 150% of the flight time if no power outlet is provided.
Batteries larger than 100Wh demand airline permission, so check the label. Carry copies of equipment manuals so staff can confirm compliance quickly.
When allowed vs. when not
✅ When it's allowed
- •Carry extension hoses and filters in sealed bags so they stay sterile.
- •Label each battery with Wh rating for easy inspection.
- •Download airline special assistance forms and keep them offline.
🚫 Exceptions / conditions
- •Don’t rely on in-seat power without confirming the voltage/amperage—you could trip the circuit.
- •Don’t place devices on the floor during take-off/landing unless strapped—they become projectiles.
- •Avoid packing CPAP masks in checked baggage; replacements abroad are expensive.
At the airport and onboard
- ✔Place the CPAP or concentrator in a separate tray for screening.
- ✔Keep hoses and masks in clean pouches to avoid contamination at security.
- ✔If using onboard, wait until cruising altitude and inform the lead cabin crew.

Travel tips
- ✈️Pack a universal adapter if travelling internationally; ground hotels may have different sockets.
- ✈️Use a travel-sized CPAP bag with TSA-friendly flaps to keep hoses organised.
- ✈️Mark hoses with coloured tape so they don’t get mixed with other medical gear.
