In other words, even though they mostly flew HKG-SYD, they did have other trips as well, and no one flight attendant was dedicated to just one route. A flight attendant's routes are generally based on a combination of bidding and seniority and aren't guaranteed. Image courtesy of Shutterstock.

Generally, flight attendants do not have set routes in the way a bus driver might; their schedules are highly variable and determined by a "bidding" system based on seniority. Each month, flight attendants "bid" for specific trips, layover cities, or days off. High-seniority crew members can often secure "regular" routes, such as a New York to London rotation, because they prefer the routine or the specific destination. Junior flight attendants, however, often work "on reserve," meaning they are on call and can be sent anywhere the airline flies on short notice to cover for sick leave or operational changes. Even for those with "lines" (set schedules), the routes change from month to month based on the airline's seasonal needs. While some might specialize in international long-haul or domestic short-haul, most crew members see a wide variety of cities throughout their careers, making the job ideal for those who crave variety rather than a fixed daily path.
