African can work more efficiently than the default maintenance provider, but the price is more expensive.
The question is, by how much?
I would like to know from your experience how much percentage-wise I am looking to pay in maintenance by switching to African from the default maintenance provider (considering no flight/schedule changes).
You get what you pay for but mostly it comes down to the type of airline you're running. With a lot of regional flights you want the top-of-the-line. If your doing international flights where you can only get one leg there and one back you can afford to be skimpy. I've just always gone with the best.
