If you are flying with a powered wheelchair or mobility aid, you may come across the WCLX airline code. WCLX is used for a wheelchair or mobility aid when its lithium battery is removed for transportation.
The code helps airline and ground-handling staff identify the battery arrangement so the mobility aid and removed battery can be prepared and transported correctly. You can also read my guide to airline disability codes for an overview of other codes you may see when arranging assistance.

This guide explains what WCLX means, how it differs from WCLB and other wheelchair battery codes, and what information to have ready before flying.
Battery rules and airline procedures can change. This guide was checked against IATA’s 2026 guidance. Always confirm the current requirements for your specific wheelchair, battery, airline and route before travelling.
What Does the WCLX Airline Code Mean?
The WCLX airline code identifies a wheelchair or mobility aid with a lithium battery that has been removed for transportation.
IATA’s 2026 guidance lists the WCLX code among the special handling codes airlines use to communicate the type and battery arrangement of a wheelchair being transported. The guidance describes the WCLX code as a wheelchair or mobility aid with its lithium battery removed for transportation.
The WCLX airline code describes the mobility equipment and battery arrangement. It does not, by itself, describe how much physical assistance a passenger needs at the airport or when boarding the aircraft.
Is the WCLX Code an SSR Airline Code?
You may hear the WCLX airline code described as an SSR, or Special Service Request, code because airlines use it within booking and service systems. IATA’s current mobility-aid guidance refers to WCLX as a special handling code.
For passengers, the important point is that the WCLX SSR code communicates information about the wheelchair and its lithium battery. If you also require assistance moving through the airport, boarding or reaching your aircraft seat, additional assistance information may be recorded separately. To learn more about the type of help you can get at the airport, refer to my dedicated special assistance guide.
What Type of Wheelchair Does the WCLX Airline Code Cover?
The WCLX airline code relates to a wheelchair or mobility aid powered by a lithium battery where that battery is removed for transportation. Do not assume that every removable wheelchair battery automatically means the WCLX code will apply. The airline needs to assess the actual mobility aid, battery and transport arrangement under the applicable dangerous-goods requirements.
Check the battery label, wheelchair manual or manufacturer’s documentation before contacting the airline. Accurate information is much more useful than trying to guess the correct code yourself. It might be useful to create a factsheet about your wheelchair that you can refer to anytime you need to give over information about it.
The WCLX Airline Code vs the WCLB SSR Code
The WCLX SSR code and the WCLB airline code both relate to lithium-powered wheelchairs and mobility aids, but the difference is whether the lithium battery is removed for transportation.
| Code | General Meaning |
|---|---|
| WCLB | Wheelchair or mobility aid with the lithium battery installed. |
| WCLX | Wheelchair or mobility aid with the lithium battery removed for transportation. |
This distinction matters because a removed lithium battery has different handling and carriage requirements from a battery that remains securely installed in the mobility aid.
For more detail about the other lithium-battery arrangement, read my guide explaining the WCLB airline code.
WCLX vs WCBD, WCBW and WCMP
Airlines use different codes to distinguish between wheelchair battery types and manual mobility aids. Some of these codes refer to the type of equipment a passenger is carrying, while others describe the type of help the passenger needs to travel safely.
| Code | General Meaning |
|---|---|
| WCLX | Wheelchair or mobility aid with lithium battery removed for transportation. |
| WCLB | Wheelchair or mobility aid with installed lithium battery. |
| WCBD | Wheelchair or mobility aid powered by a non-spillable, nickel-metal hydride or dry battery. |
| WCBW | Wheelchair or mobility aid powered by a wet-cell, spillable battery. |
| WCMP | Manual wheelchair or mobility aid. |
You can read my separate guides to the WCBD code, WCBW code and WCMP code if you need to compare the different wheelchair categories.
Does WCLX Mean I Get Wheelchair Assistance at the Airport?
No. The WCLX airline code communicates information about your own mobility aid and its lithium battery. It does not tell airport staff whether you can walk long distances, climb aircraft stairs or independently reach your seat.
A separate assistance code such as WCHR, WCHS or WCHC may also be relevant depending on your mobility needs. Tell the airline what you can and cannot do rather than trying to choose an assistance code yourself.
My guide to getting help at the airport with a disability explains more about airport assistance.
Do You Need to Tell the Airline in Advance?
Yes. Contact the airline in advance when travelling with a battery-powered wheelchair or mobility aid. The carrier may need detailed technical information before it can confirm how the equipment and battery will be transported.
Do not wait until check-in if you can avoid it. Airline procedures and notification deadlines vary, so check the requirements for your carrier and route as early as possible.
You can also submit service requests via the PRM Assist app, but I would recommend you follow that up with a phone call or email to your airline to explain your needs in more detail.
What Information Might the Airline Ask For?
Have accurate information about both the mobility aid and battery available when you contact the airline. This may include:
- Wheelchair or mobility aid make and model.
- Length, width and height.
- Total weight.
- Battery type.
- Battery voltage and capacity.
- Watt-hour rating where relevant.
- Whether the battery is designed to be removable.
- Instructions for safely removing and reinstalling the battery.
- Instructions for switching off or isolating the mobility aid.
- Manufacturer documentation requested by the airline.
A simple wheelchair information sheet can make this easier. Keep the manufacturer’s instructions available and consider carrying both digital and printed copies. I find it helpful to use a Google drive to store important documents for travelling so I can access them anywhere I have mobile data or an internet connection.
Why Would a Lithium Battery Be Removed?
Whether a lithium battery remains installed or is removed depends on the design of the mobility aid and the applicable transport requirements. IATA guidance distinguishes between lithium batteries that remain installed and batteries removed for transportation.
Do not remove a wheelchair battery simply because you have seen the WCLX code mentioned online. Follow the manufacturer’s instructions and the arrangements confirmed by your airline.
Where Does a Removed Lithium Battery Travel?
Removed lithium mobility-aid batteries are subject to specific aviation safety requirements. Depending on the battery and applicable rules, the airline may require the removed battery to be protected against damage and short circuit and transported in the passenger cabin.
Do not place a removed wheelchair lithium battery into checked baggage unless your airline has specifically confirmed that this is permitted under the applicable rules. Ask the airline exactly how your battery will be handled before travelling.
What Is the Watt-Hour Rating?
The watt-hour rating, usually shown as Wh, describes the battery’s energy capacity. Airlines may ask for this because lithium battery transport requirements can depend on battery capacity and configuration.
Look for the Wh figure on the battery label or in the manufacturer’s documentation. If you cannot find it, ask the manufacturer or supplier rather than guessing.
How Should a Removed Lithium Battery Be Protected?
Lithium batteries removed from mobility aids need protection against short circuit and physical damage. The airline may give you specific packing instructions based on the battery and its design.
Follow the manufacturer’s removal instructions carefully. Never improvise by dismantling battery housings or altering electrical connections that are not designed for passenger removal.
Can You Take a Spare Lithium Wheelchair Battery?
Additional lithium batteries for mobility aids are subject to aviation dangerous-goods requirements, including limits that can depend on battery capacity. If you need to travel with a spare, tell the airline in advance and provide the battery specifications it requests.
Do not assume the rules for an ordinary power bank or laptop battery apply to a wheelchair battery. Mobility-aid batteries have specific provisions.
Prepare a Wheelchair Handling Information Sheet
A handling sheet can help ground staff understand your wheelchair quickly. Include the make and model, dimensions, weight, battery details and clear instructions for safely moving the chair.
For a WCLX mobility aid, clearly explain how the battery is removed and reinstalled according to the manufacturer’s instructions. Also explain how to place the wheelchair into freewheel or manual mode and identify safe lifting points.
Protecting Your Wheelchair Before the Flight
- Photograph the wheelchair before handing it over.
- Remove loose accessories where appropriate.
- Protect or remove detachable controls according to manufacturer guidance.
- Attach clear handling instructions.
- Label safe lifting points if they are not obvious.
- Explain how to use freewheel or manual mode.
- Keep battery and manufacturer documentation accessible.
Inspect the wheelchair as soon as it is returned after your flight. If it has been damaged or no longer works correctly, report the problem promptly through the airline or airport’s relevant process. Keep hold of any documentation you recieved in relation to your wheelchair – including any baggage tags that were placed on it or onto its carry-case. These are important when it comes to making a claim.
What Happens on Connecting Flights?
Connections can make wheelchair transport more complicated, particularly when different airlines are involved. Confirm that your mobility aid and battery details are recorded for every sector of the journey.
Ask whether the wheelchair will be transferred directly, whether you will regain access to it during the connection and whether any additional battery checks or handling arrangements apply at the transfer airport.
What if the WCLX Airline Code Is Missing From Your Booking?
Passenger-facing apps and booking confirmations do not always show every code recorded internally. If you cannot see the WCLX code and believe it should be added to your booking, contact the airline and ask it to confirm the mobility aid and battery information it has recorded.
If the WCLX code appears but your lithium battery will remain installed, or the battery information is otherwise incorrect, contact the airline and provide the correct manufacturer information. Accurate battery details matter because the handling requirements differ.

No. WCLX describes the mobility aid and battery arrangement. Separate assistance information may be recorded to describe how much help you need through the airport and when boarding.
Should I remove my lithium wheelchair battery before flying?
Do not automatically remove it. Whether removal is required depends on the mobility aid, battery and applicable transport rules. Follow the manufacturer’s instructions and the arrangements confirmed by your airline.
Will the airline ask for my battery’s watt-hour rating?
It may. Keep accurate battery specifications available and provide the watt-hour rating and other manufacturer information if the airline requests them.
Do I need to notify the airline in advance?
Yes. Powered mobility aids can require advance assessment and preparation, so contact the airline early and follow its published notification requirements.
Understanding what WCLX means can help you prepare your powered wheelchair correctly for air travel and make sure the airline has the information it needs before your journey. WCLX identifies a wheelchair or mobility aid with a removable lithium-ion battery, which means specific battery removal, protection and transport requirements may apply. Contact your airline well in advance with details of your wheelchair and battery, and always check the airline’s current requirements rather than assuming the same arrangements will apply across different carriers or aircraft.
Continue Learning About Airline Codes
The WCLX airline code is just one of several Special Service Request (SSR) codes airlines use to record a passenger’s medical, disability or assistance needs. Other codes can indicate different wheelchair types or assistance, reduced mobility, visual or hearing impairments, travelling with an assistance dog, or other support requirements. There are even codes for which type of meal you want to order and many other codes used within the airport and by airlines.
Understanding these SSR codes can make it easier to check that the right assistance has been added to your booking. You can explore my guides to airline SSR disability codes to learn what the different codes mean, when they are used and what support you may need to arrange before you fly.
