Pilots do not get to "choose" their base in the traditional sense; instead, they "bid" for a base based on their seniority within the airline. When a pilot is hired or when new base openings occur, they submit a list of their preferred locations (domiciles). The airline's automated system then assigns the bases starting with the most senior pilot down to the most junior. This means that "junior" pilots often end up at the least desirable bases—such as those with a very high cost of living or remote locations—until they gain enough years of service to successfully bid for their home city. In 2026, with the high demand for pilots, some airlines are offering "base guarantees" as a recruitment tool to attract experienced captains, but for the majority of the industry, your base is a direct reflection of your rank and time with the company.
