Flightbunny,
Ground crew consist of boys and girls. Generally the position includes customer service, baggage handling and marshalling duties. Its a great way to learn a lot about the workings of DJ as you will see the procedures at work from a number of different perspectives. As with all DJ staff, you need to be prepared to work (seven day stints at times during the roster I believe) but ask anyone who works there and they'll tell you that DJ are a great bunch of people to work with and that the can-do attitude is unbelieveable.
Go for it.
