CSA stands for which of the following?

• A. Customer Support Agent
• B. Customer Service Agent
• C. Cabin Service Attendant
• D. Client Services Administrator

Answer: (B)

In airline settings, CSA refers to the Customer Service Agent—the airport staff member who helps passengers with check-in, ticketing, boarding, and general travel questions at counters, gates, and other customer touchpoints. This ground-based, front‑line role is all about assisting travelers and resolving issues before they fly. A Cabin Service Attendant, by contrast, is the onboard crew member responsible for safety and service inside the aircraft during the flight, which is a different function. The other options describe roles that aren’t the typical airline title for the airport customer-facing position, such as a corporate or back-office role or a generic support title. So, the best match in this context is Customer Service Agent.
