Mobility Scooter / Wheelchair

Allowed. You can use your wheelchair or mobility scooter right up to the aircraft door, and it does not count against your carry-on or checked baggage allowance — airlines must transport it free of charge. It is typically gate-checked or stowed in the cargo hold for the flight rather than brought into the cabin.

Allowed with conditions, based on the battery type. Non-spillable (gel-cell/AGM) batteries can usually stay installed if they are securely attached and the terminals are protected from short-circuit. Spillable, wet-cell (lead-acid) batteries generally must be removed and packed upright in rigid, protective packaging. Lithium-ion batteries are limited to 300 Wh installed (or one 300 Wh spare, or two spares up to 160 Wh each, carried in carry-on only — never checked). Lithium-metal (non-rechargeable) batteries aren't permitted on these devices at all. Airlines can apply stricter rules, so confirm your device's battery chemistry and watt-hour rating with your airline before you fly.
