What are you talking about???
Sponsorship from airlines such as Atlantic flight training, air 2000 and brit mid, etc require that you have a PPL BEFORE you start applying for sponsorship with them! It is only BA with whom for sponsorchip you do not require a PPL.
Go for it mate. Whatever happens, you will be better off with a PPL than not. If you do not get sponsorship for any reason then you can build on your PPL skills gaining a CPL and join the airlines direct entry.
