I've been thinking about it but the issue is that I wont be able to got a CPL, but rather a MPL with CPL privileges. And im not sure if the airlines will have the same attitude towards it as if there were no CPL privileges, since after all, it's still a MPL.
It used to be like what youre referring to that MPL students were only allowed to fly with their "host airline" but it was changed a while back.
