As part of the larger British Airways team, Operations Agents have to perform many different duties in their work. One important facet of the work can be seen as very advanced shipping and receiving duties, where you would be accepting shipments, overseeing the loading and unloading of freight, and tracking luggage that is loaded and unloaded from the fleet airplanes. If you have direct experience in any shipping/receiving settings, that is great and be sure to talk about that experience. If you don't have direct experience, just be open and honest with your interviewer and let them know that you possess the organizational and technical skills to be trained and learn this aspect of the job quickly.
