What physical demands do fleet service agents commonly face?

Fleet service agents are primarily tasked with handling the physical aspects of aircraft operations, which include lifting heavy bags and navigating various weather conditions. This role involves transporting luggage between the terminal and the aircraft, requiring significant physical strength and the ability to handle heavy items safely. Additionally, fleet service agents often work outside in different weather environments, meaning they must be prepared to perform their duties whether it's hot, cold, or inclement weather.

The other options pertain to skills or tasks that are not typically the main focus of a fleet service agent's responsibilities. Typing for long hours relates more to desk jobs and clerical work rather than the physical demands of the position. Maintaining customer records is also more aligned with administrative roles. Similarly, restocking in-flight supplies, while part of the airline operation, is usually handled by different staff members such as cabin crew or dedicated supply teams, and does not encompass the primary physical requirements of fleet service agents. Therefore, the correct response highlights the essential physical nature of the job.
