If you have seen the WCBD airline code on a flight booking or while arranging wheelchair assistance, it is an airline code used for certain battery-powered wheelchairs and mobility aids.
WCBD is used when a wheelchair or mobility aid is powered by a non-spillable battery, nickel-metal hydride battery or dry battery. It is a Special Service Request, or SSR, code that helps airline and ground-handling teams identify the type of mobility equipment being transported.

The WCBD airline code describes the equipment and battery. It does not, by itself, tell the airline how much personal wheelchair assistance you need through the airport.
What Does WCBD Stand For?
The WCBD airline code is the handling code for a wheelchair or mobility aid powered by a non-spillable, nickel-metal hydride or dry battery. The code appears in IATA guidance for battery-powered wheelchairs and mobility aids. Airlines use it to communicate the type of battery fitted to a passenger’s mobility equipment so staff can prepare and handle it correctly.
Knowing the correct battery type matters because different battery technologies have different transport and safety requirements.
What Type of Battery Does The WCBD Airline Code Cover?
WCBD can apply to mobility aids powered by:
- non-spillable batteries;
- nickel-metal hydride batteries; and
- dry batteries.
IATA’s 2026 mobility-aid guidance gives examples of dry batteries including alkali-manganese, zinc-carbon, nickel-cadmium and nickel-metal hydride types.
Many powered wheelchairs use sealed or non-spillable batteries, but you should not guess which category your battery belongs to. Check the wheelchair or battery documentation, or contact the manufacturer if you are unsure.
Is WCBD the Same as a Dry-Cell Wheelchair Code?
You may see WCBD described more simply as the code for a wheelchair with a dry-cell battery. That description is useful as shorthand, but current IATA guidance is broader.
The WCBD airline code also covers non-spillable and nickel-metal hydride batteries. This is why it is better to confirm the actual battery type rather than relying only on a short description in a booking system.
What Is the Difference Between The WCBD, WCBW and WCLB airline codes?
Airlines use different codes depending on the battery fitted to the wheelchair or mobility aid.
- WCBD – non-spillable, nickel-metal hydride or dry battery.
- WCBW – wet-cell or spillable battery.
- WCLB – mobility aid with an installed lithium battery.
- WCLX – mobility aid where a lithium battery is removed for transport.
- WCMP – manual-powered wheelchair or mobility aid rather than a battery-powered chair.
These codes help ground staff understand what they are handling. They are particularly important for powered mobility aids because battery type affects the precautions needed during air transport.
Does WCBD Mean You Need Wheelchair Assistance at the Airport?
Not necessarily. The WCBD airline code identifies your mobility aid and its battery type. It does not describe the level of assistance you need as a passenger.
If you also need help through the terminal or when boarding, the airline may add another wheelchair disability SSR code to your booking. Common examples are:
- WCHR – wheelchair assistance for airport distances, while the passenger can manage steps and reach the cabin seat independently;
- WCHS – the passenger cannot manage aircraft steps but can reach the cabin seat independently; and
- WCHC – the passenger needs the highest level of wheelchair assistance, including help to or from the cabin seat.
A passenger can therefore have WCBD and a separate mobility-assistance code on the same booking. Learn more about the different types of codes airlines and airports use.
What Information Should You Give the Airline?
IATA advises passengers travelling with battery-powered mobility aids to make arrangements with the airline in advance and provide enough information for the equipment to be accepted and loaded safely.
Airlines may ask for:
- the make and model of the wheelchair or mobility aid;
- its length, width and height;
- its total weight;
- the battery type;
- instructions for switching the chair off or isolating the battery;
- whether the battery can or must be removed;
- instructions for freewheeling or releasing the brakes; and
- safe lifting or handling points.
Keep this information clear and easy to find. Manufacturer instructions can be particularly useful if airport staff are unfamiliar with your model of chair. It can be helpful to create a factsheet about your mobility aid and save it to a Google drive so you can always access it anytime you need to give a travel provider information about your device.
Do WCBD Wheelchairs Need Advance Notice?
Battery-powered wheelchairs can require advance preparation, so contact the operating airline before travel rather than waiting until you arrive at the airport. IATA guidance notes that powered mobility aids may require preparation, disassembly or other handling arrangements. Airlines can also have their own notification procedures, so check the deadline given by your carrier.
If your itinerary involves more than one airline, check the requirements with each operating carrier. Do not assume that information provided to the airline selling the ticket has automatically answered every handling question for the other carriers.
Does the Battery Have to Be Removed?
Not in every case. The correct procedure depends on the wheelchair design, battery type, how securely the battery is fitted and the applicable dangerous-goods rules. For many non-spillable battery-powered wheelchairs, the battery can remain fitted when the mobility aid can be loaded, secured and protected appropriately. Airlines still need to ensure that accidental activation is prevented and that the equipment is safe for transport.
Do not remove or disconnect components simply because you think the airline will require it. Follow the manufacturer’s instructions and the directions given by the operating airline.
How Can You Find Out What Battery Your Wheelchair Uses?
If you do not know your battery type, check before contacting the airline. Useful places to look include:
- the wheelchair user manual;
- a label on the battery or battery housing;
- the manufacturer’s website;
- the mobility dealer or wheelchair service that supplied the chair; and
- the battery manufacturer’s technical information.
Ask for the exact battery chemistry rather than only a brand name. This helps the airline decide whether WCBD or another battery code applies.
What Happens to a WCBD Wheelchair at the Airport?
The procedure varies between airports and airlines. You may be able to remain in your own powered wheelchair through most of the airport and transfer closer to boarding, but local arrangements differ. Before the chair is taken for loading, staff may check the battery information, confirm how to switch the chair off, inspect how the battery is secured and ask about freewheel or brake-release controls.
Ask where your wheelchair will be returned at your destination. If you need it at the aircraft door rather than baggage reclaim, make that request clear when arranging assistance and confirm it again at the airport. Learn more about airport special assistance in my dedicated guide so you know what to expect on the day.
Preparing a Battery-Powered Wheelchair for a Flight
A small amount of preparation can make it easier for ground staff to handle your mobility aid correctly.
- Take photographs of the wheelchair before it is handed over.
- Remove loose accessories where practical and permitted.
- Label removable parts.
- Attach or carry clear handling instructions.
- Show how to switch the chair off and put it into freewheel mode if necessary.
- Identify safe lifting points and places that should not be used for lifting.
- Keep the make, model, dimensions, weight and battery details readily available.
If the wheelchair is damaged or not returned as expected, report the problem to the airline or its ground-handling team as soon as possible.
The WCBD Airline Code and Airport Special Assistance
Equipment handling and passenger assistance are related but separate parts of an accessible journey.
When speaking to the airline, explain both the wheelchair you are bringing and the support you need. Tell staff whether you can walk short distances, use steps, transfer independently or need an aisle chair to reach your seat.
You may also encounter the term PRM, meaning Person with Reduced Mobility. My guide to what PRM means for disabled travellers explains how this broader term is used in accessible travel.
