If you are flying with a powered wheelchair or mobility aid, you may see the WCLB airline code on your booking. WCLB is an airline special handling code used for a wheelchair or mobility aid with an installed lithium battery.
The code helps airline staff understand what type of mobility aid is being transported so it can be prepared and handled under the correct battery-safety procedures. You can read into other airline disability codes in my guide so you can figure out which one suits your situation best.

This guide explains what the WCLB airline code means, when it is used, what information you may need to give the airline and how it differs from WCBD, WCBW, WCMP and WCLX.
Battery rules and airline procedures can change. This guide was checked against IATA’s 2026 guidance. Always confirm the requirements for your specific wheelchair, battery, airline and route before travelling.
What Does WCLB Mean?
WCLB is used for a wheelchair or mobility aid with an installed lithium battery.
IATA’s 2026 guidance lists WCLB as one of the special handling codes airlines use to communicate the type of wheelchair being transported. It distinguishes lithium-powered mobility aids from wheelchairs using other battery types.
WCLB does not describe how much personal assistance the passenger needs in the airport. It describes the battery-powered mobility aid being transported.
For a broader overview of airline accessibility abbreviations, read my airline and airport disability codes guide.
Is WCLB an SSR Code?
The WCLB airline code is used in airline reservation and handling systems to identify a lithium-battery wheelchair or mobility aid. You may hear it described alongside Special Service Request, or SSR, codes, although IATA’s mobility-aid guidance refers to WCLB as a special handling code.
For passengers, the practical point is the same: the code helps communicate that the mobility aid has an installed lithium battery and therefore needs the correct preparation before loading.
What Type of Battery Does WCLB Cover?
WCLB is used for a wheelchair or mobility aid with a lithium battery installed in the device.
Lithium batteries are common in powered wheelchairs, folding powerchairs, mobility scooters and power-assist devices because they can provide substantial energy without the weight of some older battery technologies.
Do not assume a powered wheelchair uses lithium simply because it is rechargeable. Check the battery label, user manual or manufacturer documentation.
WCLB vs WCLX
WCLB and WCLX both relate to lithium-powered mobility aids, but they describe different transport arrangements.
WCLB stands for wheelchair with a lithium battery. The WCLB airline code means the mobility aid has an installed lithium battery.
WCLX stands for wheelchair with a removed lithium battery. The WCLX code is used when the lithium battery has been removed from the mobility aid for transportation.
Whether a battery stays installed or must be removed depends on the design of the mobility aid, how well the battery is protected against damage and the applicable dangerous-goods rules.
WCLB vs WCBD
WCBD means the wheelchair has a dry, non-spillable or other specific battery. The WCBD code is used for a wheelchair or mobility aid powered by a non-spillable battery, nickel-metal hydride battery or dry battery.
WCLB means the wheelchair has a lithium battery. The WCLB airline code is specifically for an installed lithium battery. The correct code matters because the preparation and battery-safety rules are not identical.
WCLB vs WCBW
WCBW stands for a wheelchair with a spillable or wet battery. The WCBW code identifies a wheelchair or mobility aid powered by a wet-cell, spillable battery. A wheelchair that uses wet-cell batteries can leak corrosive electrolyte if they are not kept upright.
WCLB identifies a lithium-powered mobility aid. The WCLB airline code means the lithium batteries aren’t spillable like WCBW batteries but have different safety concerns and transport requirements.
WCLB vs WCMP
WCMP means that the wheelchair is manually powered. The WCMP code is used for a manually powered wheelchair or mobility aid.
WCLB stands for a wheelchair with a lithium battery. The WCLB airline code is used for a mobility aid with an installed lithium battery.
If you use a manual wheelchair with a removable powered add-on or power-assist device, tell the airline about both parts. The airline may need separate information about the chair and lithium-powered equipment.

Do You Need to Tell the Airline About a WCLB Wheelchair in Advance?
Yes, you should notify the airline in advance when travelling with a lithium-powered wheelchair or mobility aid.
IATA guidance states that WCLB mobility aids require advance notification and preparation. Airlines may ask for the wheelchair’s weight and dimensions as well as detailed battery information. It can be helpful to prepare a factsheet with information about your wheelchair if you intend to travel so you have a quick reference guide for any questions which may come up. I recommend storing these in a Google drive so you have access to them wherever you are.
Contact the airline as early as possible rather than waiting until check-in. This gives its dangerous-goods or special assistance teams time to review the mobility aid and confirm what is required.
What Information Will the Airline Need?
Airlines commonly ask for information that allows staff to identify and safely handle the wheelchair and battery.
- The wheelchair or mobility aid make and model.
- Length, width and height.
- Total weight.
- Battery type.
- Battery voltage and capacity.
- The watt-hour rating where relevant.
- Whether the battery is removable.
- How the electrical circuits are isolated.
- How the wheelchair is placed into safe or freewheel mode.
- Where safe lifting and tie-down points are located.
Providing the manufacturer’s manual or an air-travel information sheet can make this process easier.
What Is a Wheelchair Air Travel Information Card?
An air travel information card or factsheet gives baggage and loading staff practical information about your mobility aid. It can include the wheelchair’s dimensions, weight, battery details, isolation method and instructions for moving or lifting it.
IATA encourages clear information-sharing because powered mobility aids vary significantly. Staff cannot safely assume that two electric wheelchairs operate in the same way.
Keep a copy with the mobility aid and another copy with your travel documents where possible.
Does the Lithium Battery Stay in the Wheelchair?
It can, provided the mobility aid and battery meet the conditions for safe transport with the battery installed.
IATA’s 2026 guidance states that battery-powered mobility aids must be prepared to prevent unintentional activation and the battery terminals must be protected from short circuit.
The battery can remain securely attached when the electrical circuits can be isolated according to the manufacturer’s instructions and the battery is adequately protected against damage. If the design does not provide adequate battery protection, the battery may need to be removed according to the manufacturer’s instructions.
What Happens if the Battery Must Be Removed?
If a lithium battery must be removed from the mobility aid for transportation, the handling arrangements change. This is where the WCLX code may be more relevant than the WCLB airline code.
Removed lithium batteries are subject to specific packing, terminal-protection and cabin-transport requirements. Do not remove a battery at the airport unless you understand the manufacturer’s instructions and the airline has confirmed what it expects.
What Is the Watt-Hour Rating?
Airlines may ask for the battery’s watt-hour rating, usually written as Wh. This is a measure of the battery’s energy capacity and is important in lithium-battery transport rules. The watt-hour rating may be printed directly on the battery label. If it is not obvious, check the manufacturer’s documentation rather than guessing.
Some airlines may also request a battery data sheet or other manufacturer documentation as part of their approval process.
Can You Bring Spare Lithium Wheelchair Batteries?
Spare and removed lithium batteries are subject to stricter limits and handling rules than an installed battery. The exact arrangement depends on the battery configuration and its watt-hour rating.
Do not assume that a spare battery can simply be placed in checked baggage. Contact the airline before travel and follow the current dangerous-goods requirements for mobility-aid batteries.
How Should the Wheelchair Be Prepared for the Flight?
The key requirement is preventing accidental operation and battery short circuits during transport.
The airline may need to know how to:
- Switch the mobility aid off safely.
- Isolate the electrical circuits.
- Protect controls from accidental activation.
- Put the chair into freewheel or manual mode.
- Secure or remove detachable components.
- Protect the battery from damage.
- Safely lift and move the wheelchair.
Follow your manufacturer’s instructions. Incorrectly disconnecting or handling a powered wheelchair can damage the equipment.
Can Airline Staff Disconnect the Battery?
Procedures vary, so discuss this with the airline before travel. Staff need clear manufacturer instructions for safely isolating or removing a battery. If your wheelchair has a particular isolation plug, removable key or sequence for switching it into transport mode, make sure these instructions are easy to find.
Consider attaching a clear laminated instruction sheet to the chair as well as giving the airline information in advance.
What if the Airline Asks for a Battery Safety Data Sheet?
Some airlines ask passengers for manufacturer documentation such as a battery specification sheet, safety data sheet or declaration confirming the battery type and capacity.
Check the wheelchair manufacturer’s website or contact the supplier well before travel. Keeping these documents saved on your phone and in cloud storage can be useful, but also consider carrying a printed copy in case airport connectivity is poor.
WCLB Does Not Describe Your Airport Assistance Level
This is an important distinction. The WCLB airline code tells the airline about the mobility aid and its battery. It does not tell staff whether you can walk, climb aircraft stairs or reach your seat. You may also need a separate wheelchair assistance code such as WCHR, WCHS or WCHC depending on your mobility.
For more detail, my airline disability codes guide explains the main wheelchair-assistance categories.
What Happens at Check-In?
Arrive with enough time for the airline or ground handler to inspect the mobility aid and confirm the preparation arrangements. Even when the WCLB airline code is already recorded, staff may still need to confirm the battery type, dimensions, weight and isolation method before accepting the wheelchair.
Keep your battery documentation and handling instructions accessible rather than packed in checked luggage. Again, this is when a dedicated Google drive can be really handy for storing documentation you might need access to wherever you are.
Can You Use Your Wheelchair to the Aircraft Door?
Many wheelchair users prefer to remain in their own chair for as long as possible. Whether this is possible depends on the airport, aircraft, route and operational procedures.
Ask the airline where your wheelchair will be taken from you and where it will be returned after landing. Do not assume that aircraft-door delivery is guaranteed at every airport.
What Happens on Connecting Flights?
IATA guidance notes that a WCLB wheelchair and battery may need to be claimed and rechecked at interline transfer points where agreed between airlines.
This makes advance planning particularly important on itineraries involving more than one carrier. Ask how your wheelchair will be handled at each connection and whether you will regain access to it between flights.
What if the Airline Changes Your Aircraft?
An aircraft change can affect cargo-door dimensions and available hold space. A wheelchair accepted on one aircraft type may be more difficult to load onto a smaller replacement aircraft.
If you receive notification of an aircraft or itinerary change, reconfirm the wheelchair details and WCLB airline code arrangements with the airline.
How to Reduce the Risk of Wheelchair Damage
Air travel can expose mobility aids to unfamiliar handling, so clear preparation matters.
- Photograph the wheelchair before handing it over.
- Remove loose cushions or accessories where appropriate.
- Secure or remove detachable controls according to manufacturer guidance.
- Attach clear handling instructions.
- Label safe lifting points.
- Explain how to disengage and re-engage the motors.
- Keep the chair’s make, model and serial number available.
If anything is damaged, report it to the airline or baggage services as soon as possible and keep photographs and paperwork.
