Any airline that wants to be successful in the long run and wants to achieve a certain level of growth will need pilots to fly for them over time. This is the only way to ensure that all routes are fully utilized and that the planes keep moving. The more pilots an airline has, the more routes it can serve without fear of a decline in TPI. However, as the size of an airline increases, the administrative work around the airline can also become more extensive. Stressed-out CEOs find support by having pilots promoted to managers and granting them individual powers.
