D'K -
* finish school to year 12 (preferable)
* clock up some customer service experience in hospitality for a few years
* apply for an airline. you will need an RSA and first aid cert - but you should already have an RSA working in hospitality.
Three years customer service experience face to face in challenging environments is one of hte best things you can have on your resume. There is a chance you can get in sooner, but most recruiters want experience and also a bit of life experience too (travel/work etc)
