Fly-in Spain's a dump.
Customer service is zero...
Rates are pricey... Landing fees will bite you on the ars3... ground breifings are sketchy (meaning you'll need to pay for more flying time because things weren't clear before the lesson). One of the younger - but for some reason more senior ground instructor's in particular, is totally unaproachable, foul mouthed and unsympathetic to the point I'm aware of some customers refusing to fly with him. (And I don't mean either of the chaps called Gary, to be fair).
The school owner is unflexible, greedy and arrogant (and not actually a CFI, if that's of any consequence to some potential customers)... the list goes on...
oh, I know it's a familiar old story... you decide. But start with the website and you'll get the idea...
