If she had a "bad experience" in Spain, she better wear a longer skirt if she wants to train in the UK
because the instructors are just the same.
Unless of course the bad experience is entirely different from what I am thinking of.
Personally, I would do the JAA PPL in Spain, because it will be done far quicker. Here in the UK, you can get lucky but more likely not, especially at this time of the year. If one flies every day, the retention is a lot better and it's possible to do it in 6 weeks or even less.
