👂 Hearing Aid

You can keep your hearing aid in during security screening — it will not trigger the metal detector in any meaningful way, and screeners are trained to expect medical devices. You do not need to remove it or declare it unless you want to. If you do set off an alarm, simply tell the officer you are wearing a hearing aid and they will adjust their screening approach.

Hearing aids are universally permitted in cabin and checked baggage with no restrictions anywhere in the world. Spare hearing aid batteries — including lithium button cells — are also permitted in carry-on across all major regions. There are no regional differences to worry about for this item.

Airlines do not require any special declaration for hearing aids, and cabin crew are used to passengers who wear them. If you let the airline know at booking that you use a hearing aid, they can note it on your booking so crew are aware and can communicate with you appropriately — but this is a service consideration, not a requirement.

Spare batteries, including lithium button cells used in many hearing aids, should go in carry-on baggage. Lithium batteries in general are better transported in the cabin where any thermal event can be quickly managed. There is no quantity restriction for personal-use hearing aid batteries in carry-on.
