Pilot Seniority and Domiciles – Where You’re Based as a Pilot
Domiciles are one of the first things pilots choose. An airline domicile, sometimes called a crew base, is where the flight crew is permanently based. This means that all flight schedules for that crew begin and end at this location. As with most things, domicile assignment is based on pilot seniority. When first entering the airline during ground training, pilots will select multiple domiciles they would like to be based out of in preferential order. The airlines then assign those domiciles in order of seniority. The most desirable bases go to those highest on the seniority least.
Pilots can either choose to live in the same location as their domicile or they can choose to commute there using their flight benefits. However, the lower you are on the seniority list, the harder it may be to commute to your domicile. Many pilots work their way into their most desirable domicile as they gain higher seniority over time.
