Who ever told you stay with Cabair because of possible interviews in the future with airlines, in my opinion is not good advice. For your PPL chose a school you find you like. Airlines really look at your more advance training. The would rather hear from you in the interview i chose this school for my PPL because they suited me more than others, friendly etc rather than I chose Cabair cause I thought it would sound better on my CV. Don’t get me wrong i am not putting Cabair down I am just saying open your mind a bit more to other schools and you may find a better price. In the end of the day a good flying school will get you a PPL and a PPL is a PPL.
