Which of the following is a key responsibility of a ramp agent during aircraft servicing?

A key responsibility of a ramp agent during aircraft servicing is loading and unloading baggage. This task is critical for ensuring that all the luggage is securely stowed in the aircraft before departure and safely retrieved upon arrival. The ramp agent must handle baggage with care to prevent damage and ensure that the correct luggage is loaded onto the appropriate flight, as well as manage the timely turnaround of the aircraft.

This activity plays a fundamental role in the overall efficiency of airport operations, contributing to on-time departures and maintaining the flow of air travel. In contrast, option B pertains to services that occur inside the aircraft and are not part of the ramp agent's duties. Option C involves the scheduling of flights, which is managed by operations and dispatch teams rather than ramp agents. Option D relates to customer interactions at the ticketing or check-in phase, which falls under the responsibilities of customer service agents. All these roles are essential but clearly distinct from the primary functions of a ramp agent.
