When you are first hired in 2026, you generally cannot "choose" your home base; you are assigned one based on the "operational needs" of the airline. During your initial training, the airline will provide a list of available bases (e.g., London Heathrow vs. Manchester, or New York JFK vs. Dallas/Fort Worth), and you will "bid" on your preferences. However, assignments are almost always handed out based on seniority or the specific vacancies at that moment. New hires often end up at the "junior bases" where the cost of living might be higher or the routes less desirable. Once you have finished your probationary period, you can put in a "transfer request" to move to your preferred base. Depending on the airline's size and the popularity of the base, a transfer could happen in a few months or take several years. While you can't strictly choose your base on day one, most airlines try to accommodate preferences as soon as seniority allows.
