01The rules in detail
Airlines must carry mobility aids at no charge. CPAP and BiPAP machines are medical devices exempt from carry-on limits (bring the prescription; distilled water for the humidifier is medically exempt from the 100 ml rule when declared). Powered wheelchairs: notify the airline in advance; lithium batteries have specific Wh rules and may need removal; airlines are liable for damage in the US under updated DOT rules. Canes and crutches go in the cabin. Book wheelchair assistance when you book the flight, not at the airport.
02Tips
- Photograph the wheelchair before handing it over.
- Carry CPAP in a separate bag — it doesn't count as your carry-on.
03Frequently asked
Can I bring a wheelchair or CPAP machine in my carry-on?
Yes. Assistive devices fly free and don't count toward bag allowances. Manual wheelchairs, walkers, canes and CPAP machines can go in the cabin where they fit; powered wheelchairs travel in the hold with battery rules. Request assistance 48 hours ahead.
Can I pack a wheelchair or CPAP machine in checked luggage?
Yes. Assistive devices fly free and don't count toward bag allowances. Manual wheelchairs, walkers, canes and CPAP machines can go in the cabin where they fit; powered wheelchairs travel in the hold with battery rules. Request assistance 48 hours ahead.
Are the rules the same outside the US?
Mostly similar for liquids and batteries, which follow international standards, but sharp objects, tools, lighters and self-defense items vary widely by country. Check the departure airport's rules and the destination's laws.
TSA and other agencies allow officers to refuse any item they judge unsafe, and rules change. This page summarises published guidance as of the verified date; confirm on tsa.gov or your airport's site before packing anything unusual.
