If you see the WCBW airline code on an airline booking or special assistance record, it is a Special Service Request code associated with a wheelchair or mobility aid powered by a wet-cell battery.
WCBW is different from wheelchair assistance codes such as WCHR, WCHS and WCHC. Those codes describe how much mobility assistance a passenger needs at the airport and when boarding. WCBW gives the airline information about the passenger’s battery-powered mobility equipment.

This distinction matters because powered wheelchairs and mobility aids need to be prepared and carried safely in accordance with aviation dangerous-goods rules and the airline’s procedures. Tell the airline about your mobility aid well before travel and provide accurate battery, weight and dimension information when requested.
What Does WCBW Mean?
WCBW is an airline Special Service Request, or SSR, code used for a wheelchair or mobility aid with a wet-cell battery. Learn more about SSR codes and requests if you are new to the term.
Wet-cell batteries are also described in aviation guidance as spillable batteries in relevant circumstances. They require particular handling because the battery contains liquid electrolyte and must be protected against accidental activation, short circuits and leakage.
The WCBW airline code helps communicate the type of battery-powered mobility equipment associated with the passenger’s booking.
What Is an SSR Airline Code?
SSR stands for Special Service Request. Airlines use SSR codes to pass passenger service and equipment information through reservation and operational systems.
Some SSRs describe a passenger’s mobility assistance needs. Others communicate information about equipment being carried. WCBW belongs to the latter group because it identifies a particular type of battery-powered wheelchair or mobility aid.
Our airline and airport disability codes guide explains common disability-related airline codes and what they mean.
Does the WCBW Airline Code Mean Wheelchair Assistance?
Not by itself. The WCBW airline code describes the mobility aid and its battery rather than how far the passenger can walk.
A traveller with a wet-cell battery wheelchair may also have a code such as WCHR, WCHS or WCHC recorded to describe the physical assistance they need. For example, a passenger who cannot independently reach their aircraft seat may require WCHC assistance while WCBW separately identifies the type of battery in their wheelchair.
Passengers do not normally need to work out which SSR combination should be entered. Tell the airline about both your mobility needs and your equipment and they will figure out which code suits your needs the best.
The WCBW Code Compared With WCHR, WCHS and WCHC
| Code | General Meaning | What It Communicates |
|---|---|---|
| WCBW | Wheelchair or mobility aid with wet-cell battery | Battery and equipment information |
| WCHR | Wheelchair – Ramp | Passenger needs a wheelchair for distance but can use stairs and walk to the cabin seat |
| WCHS | Wheelchair – Steps | Passenger cannot manage stairs but can walk to the cabin seat |
| WCHC | Wheelchair – Cabin Seat | Passenger needs assistance reaching the aircraft seat |
Think of the WCBW airline code as describing the wheelchair, while the WCH codes describe the passenger’s mobility assistance requirements.
What Is a Wet-Cell Wheelchair Battery?
A wet-cell battery uses liquid electrolyte. In aviation transport rules, batteries of this type can require different handling from non-spillable batteries or lithium batteries.
Do not guess your battery type based on the appearance of the wheelchair. Check the mobility aid manual, battery label or manufacturer’s technical information. If you are unsure, contact the wheelchair manufacturer or supplier before speaking to the airline. Accurate battery identification is important because the carriage requirements depend on the battery chemistry and design.
Why Does the Airline Need to Know the Battery Type?
Battery-powered mobility aids are treated differently from ordinary checked baggage. Airlines need enough information to determine how the equipment can be loaded and carried safely.
The battery type can affect whether the battery remains installed, how it must be protected and what staff need to do if the wheelchair cannot be loaded and secured in its normal upright position.
The airline may also need the mobility aid’s dimensions and weight to check that it can physically pass through the aircraft cargo door and be accommodated in the hold.
Is the WCBW Airline Code the Same as WCBD or WCLB?
No. Airlines use different SSRs to distinguish battery types used in mobility aids.
| Wheelchair Battery Code | General Meaning |
|---|---|
| WCBW | Wheelchair or mobility aid with wet-cell battery |
| WCBD | Wheelchair or mobility aid with dry-cell or non-spillable battery |
| WCLB | Wheelchair or mobility aid with lithium-ion battery |
Terminology can vary between airline systems and passenger-facing information, so describe the actual battery rather than relying solely on a code like WCBW. The airline can determine which code best suits your wheelchair and apply it to your booking.
How to Request the WCBW Airline Code on a Flight Booking
You do not normally need to contact the airline and specifically ask for the WCBW airline code to be added to your booking. If you do contact them you should instead tell the airline that you are travelling with a powered wheelchair or mobility aid and provide the battery information it requests. Airline staff can record the appropriate SSR in the booking.
Notify the airline as early as possible. Mobility equipment often requires more preparation than arranging an airport wheelchair because the carrier may need technical information about the device before accepting it for carriage.
Information to Have Ready for the Airline
Airlines commonly need detailed information about powered mobility aids. Before contacting the airline, have the following available where possible:
- Wheelchair or mobility aid make and model.
- Overall dimensions.
- Total weight.
- Battery type.
- Number of batteries.
- Instructions for switching off or disabling the device.
- Instructions for preventing accidental activation.
- Details of removable parts.
- Manufacturer’s handling or transport instructions.
The airline may ask for additional information depending on the equipment and route.
I recommend creating a handy factsheet with this information on it that you can refer to any time you make a new travel booking. Better yet, store it on a Google drive so you have access to it anywhere you have an internet connection or mobile data.
Can a Wet-Cell Battery Stay in the Wheelchair?
Whether the battery can remain installed depends on the mobility aid, how it can be loaded and secured, and the applicable aviation rules. Where a spillable battery-powered mobility aid can be loaded, stowed, secured and unloaded while remaining upright, aviation rules can allow the battery to remain installed subject to requirements such as protecting the terminals against short circuits and preventing accidental activation.
If the mobility aid cannot be kept upright, different procedures can apply and the battery may need to be removed and carried in suitable packaging.
Do not remove or disconnect a battery simply because you have read a generic instruction online. Follow the airline’s directions and the manufacturer’s safe handling instructions for your specific equipment.
Protecting the Wheelchair From Accidental Activation
Powered wheelchairs must be protected against unintended operation while in the aircraft hold. The correct method depends on the wheelchair.
It may involve a key, power switch, control sequence or another manufacturer-approved procedure. Prepare a short handling sheet showing airport staff exactly how to switch the chair off and make it safe. Photographs can be useful when controls are not obvious. Avoid instructions that require staff to guess which wires or connectors should be disconnected.
Prepare a Wheelchair Handling Information Sheet
A simple information sheet can reduce the risk of misunderstandings when your wheelchair is handed to ground staff. Include the make and model, weight, dimensions, battery type, safe power-off procedure, freewheel or manual mode instructions and your contact details.
Clearly identify any parts that should not be used for lifting. If armrests, cushions, joysticks or other components are removable, explain what should happen to them.
Attach a copy securely to the chair and keep another copy with your travel documents.
Take Photographs Before Checking In the Wheelchair
Photograph the wheelchair from several angles before handing it over. Include close photographs of the joystick, battery area and any existing marks or damage. This gives you a record of the chair’s condition and can also help explain controls to staff.
Can You Stay in Your Own Wheelchair Until the Aircraft Door?
Many wheelchair users prefer to remain in their own mobility aid until as close to boarding as possible.
Whether this can happen depends on the airport, aircraft and boarding arrangements. Ask the airline and airport assistance team what will happen on your flight.
If you need an aisle chair to reach the cabin seat, explain your transfer requirements when arranging assistance.
The WCBW Airline Code and Airport Security
A powered wheelchair still needs to pass through the airport’s security process. Screening methods vary according to the airport and the passenger’s ability to transfer or stand. Tell security staff what movements are and are not possible.
Do not disconnect or dismantle essential wheelchair components unless instructed under the relevant security and airline procedures.
Using the WCBW Airline Code on Connecting Flights
Connections add another stage where your wheelchair must be handled correctly. Confirm that the mobility aid information is recorded across every flight sector, especially when different airlines operate the itinerary.
Ask whether your wheelchair will be returned during the connection or transferred directly to the onward aircraft. The answer can depend on the airport, connection time and baggage arrangements.
Allow a realistic connection time. Loading and unloading powered mobility equipment can require additional coordination.
What if the Airline Says the Wheelchair Cannot Fit?
Aircraft cargo doors and holds have physical size and weight limitations. This can be particularly relevant on smaller aircraft. Provide accurate dimensions and weight before travel so the airline can assess the equipment against the aircraft scheduled for the route.
If the airline identifies a problem, ask for the exact restriction and what alternatives are available. Do not arrive at the airport assuming a large powered wheelchair can be carried on every aircraft type.
What if the WCBW Airline Code Is Wrong?
Contact the airline if the WCBW airline code appears on your booking but your mobility aid does not use a wet-cell battery. An incorrect battery code can cause confusion because different battery types have different carriage requirements.
Provide documentation showing the actual battery chemistry and ask the airline to correct the equipment information in the booking.
What if the WCBW Airline Code Is Missing From the Booking?
Passenger-facing airline websites and apps do not always display every SSR. The absence of a visible WCBW airline code does not necessarily mean the airline has failed to record your wheelchair.
Contact the airline and ask it to confirm the mobility aid details it has recorded, including the battery type, dimensions and weight. Keep written confirmation where possible.
What Happens if a Wheelchair Is Damaged?
Inspect your mobility aid as soon as it is returned. If you notice damage or the chair no longer operates correctly, report the problem immediately using the airline or airport’s baggage and mobility-equipment reporting process.
Keep photographs, paperwork and any report reference number. Your pre-flight photographs can help document the chair’s condition before it was handed over.
FAQ About the WCBW Airline Code
What Does WCBW Stand For in Aviation?
The WCBW airline code is the SSR used for a wheelchair or mobility aid powered by a wet-cell battery. It communicates equipment and battery information to the airline.
Does Using the WCBW Code Mean I Get Wheelchair Assistance?
Not by itself. WCBW describes a battery-powered mobility aid. A separate code such as WCHR, WCHS or WCHC may be used to communicate the passenger’s mobility assistance requirements.
What Is the Difference Between WCBW and WCHC?
WCBW identifies a wheelchair or mobility aid with a wet-cell battery. WCHC indicates that the passenger requires wheelchair assistance all the way to their aircraft cabin seat.
Do I Need to Know My Wheelchair Battery Type?
Yes. The airline may need accurate battery information to determine how the mobility aid can be transported safely. Check the battery label, wheelchair manual or manufacturer’s technical documentation rather than guessing.
Should I Remove My Wheelchair Battery Before Flying?
Do not automatically remove it. The correct procedure depends on the battery type, mobility aid and how it can be loaded and secured. Follow the airline’s instructions and the manufacturer’s safe handling guidance.
How Early Should I Tell the Airline About My Powered Wheelchair?
Notify the airline as early as possible and follow its published deadline for mobility equipment information. Powered wheelchairs can require technical checks before travel, so leaving the discussion until airport check-in can create avoidable problems.
