"If i dont get a CPL but get a PPL would an airline doing sponsorship accept me?"
There are some companies (two that i know of) that do this kind of sponsorship. They require you to have a PPL and they train you up and in return you work for them for a set amount of time. (just google something like pilot cadet scheme)
Look at Highland Airways and Atlantic Airlines/RVL. Driving licence for all the donkey work and a PPL are required.
