In the aviation industry, the codes WCHC, WCHR, and WCHS are special service request (SSR) codes defined by IATA.
They are used in airline reservation systems to indicate the type of wheelchair assistance a passenger requires.
Understanding the difference between these codes is essential for travel agents, airport staff, and airline employees to ensure smooth passenger handling and proper service.
1) WCHR – Wheelchair Ramp
Meaning:
The passenger can walk short distances and can climb or descend aircraft stairs, but needs a wheelchair for long distances inside the airport.
WCHR Features:
- Can walk short distances.
- Can use aircraft stairs independently.
- Needs wheelchair assistance from check-in to the gate.
- Does not require assistance inside the aircraft cabin.
Best for: Elderly passengers or travelers with limited walking endurance.
2) WCHS – Wheelchair Steps
Meaning:
The passenger cannot climb or descend aircraft stairs but can walk short distances inside the aircraft cabin.
WCHS Features:
- Needs wheelchair assistance within the airport.
- Requires help when boarding or disembarking (stairs or ramp).
- Can walk to their seat inside the aircraft with minimal assistance.
Best for: Passengers with mobility limitations who cannot use stairs.
3) WCHC – Wheelchair Cabin
Meaning:

Conclusion
The difference between WCHR, WCHS, and WCHC depends on the passenger’s mobility level:
- WCHR → Can use stairs, needs help for long distances only.
- WCHS → Cannot use stairs, but can walk short distances.
- WCHC → Cannot walk at all and requires full assistance.
Selecting the correct SSR code according to IATA standards ensures proper wheelchair service, passenger safety, and smooth airport operations.
If you work in aviation or travel agencies, understanding these codes is essential for accurate booking and professional service delivery.
