As you probably know things are very tight in the aviation industry at present. Any job in operations (airport or airline)requires about two/three years experience.
As you do not have any experience, one possible route is to get a position as a passenger services agent in a handling agent or airline, or a steward for about a year or two and then evaluate your options from there. The money is not at all great, you will be treated like **** by all and sundry, but if you can stomach it, it will be fully worth it.
From there you can get a job as a dispatcher or ops officer and then work your way up from there.
However, considering the cash earned in IT, the cash for these jobs are not great.
Hope I have been of some assistance, best of luck in your endeavours!!!!!
