Hi, I went for a trial lesson at Bristol and Wessex and found it to be more of a club than a school. I went away feeling like an idiot - I don't think the instructor took me seriously.
I then went for a lesson with Aeros, Filton and they were very helpful and encouraging. I trained with Aeros and now have my PPL. They are very friendly and professional, I highly recommend them. Good luck with your training.
