Worth considering how your role will fit into the "big picture" of getting passengers/freight from point A to point B. What will affect your role? How could your job impact on the next piece of the chain? It takes people within your team, and then all the teams put together, to make the process work smoothly. Re-inforce the fact that you are a proven team-player as well as somebody who can follow instructions independently.
Other than that, a good knowledge of the company and industry is always a head-start and relaxing, feeling confident and putting your points across clearly will all help.
Best of luck.
