Could try and get hold of the email address for the right person in an airline or agent or something and explain you don't have any relevant experience in the industry but want to get into it and where would they suggest you get some experience.
You'll probably not get many replies, but it would only take a few minutes to respond, so if it ends up in the right persons inbox and they're in the right mood, you may get a very useful reply.
