I would recommend trying to get work with a handling agent in your spare time to gain experience. Although i would advise against working with larger airlines as the pay is very poor and you get treated like dirt
However if you can score a job with GA FBO/Handling agents you will not only gain great experiance on both the ramp but in all areas of a/c ops, and even better loads of contacts to score that first job and i found a better career in GA and have little wish to fly for a major airline.
give it a go all the best with the future
