I'd reccomend going up to a training establishment such as Oxford or Cabair to have a look around. They will try to sell it to you but just try to stay open minded and see what you think of the environment.
If you're considering a ppl like SamKitch mentioned, not a lot of airlines will actually put you above someone else for it, but it will definately help to have that prior experience in cpl training.
The downside is, as in the all things aviation, it costs money and lots of it. So think about it.
But to have a look around oxford aviation training is not going to hurt. Give them a call
Be aware though its a different industry to what many people imagine it to be.
