Lofty Dreams, you should read thru this entire thread before embarking on your mission to get a CPL.
Do you know how many 'self sponsored' CPL/ATPL are basically stagnating -some for many years.I my self know 5 guys with ATPL working a stewards they have maxed out their interview options.
Bottom line: the majors don't like self sponsored for very obvious reasons.
You have a better chance with Jetstar/Tiger cadet scheme at STTA.
