What is a Line Holder?

A Line Holder refers to a crewmember who has been awarded a line of flying time, which is a scheduled block of flight duties that typically covers a specific period, such as a month. This means that the crewmember is assigned to a series of flights and has a defined schedule that outlines when they are on duty and when they are not. This structure is fundamental in ensuring that crew members have a reliable timetable and know their flying responsibilities in advance, which helps with planning both work and personal commitments.

Line Holders are different from those who may have more flexible schedules or who are not scheduled for any flights at a given time, as their primary role is to operate flights as per the assigned line. This concept is crucial in understanding the management of crew schedules and duties within airline operations, ensuring that service is continuous and compliant with regulations regarding crew rest and workload.
