Wow, this is really frustrating! We fly into their around 2-3 times per month, so these fee's add up! Every time I show Immigration our multi-entrence permit proving we are a private flight, as well as the documentation from the DGAC that Private flights are not to pay the overtime fee's, yet they insist the fee's are for everyone regardless of the type of flight.

Any other suggestions in setting them straight, so that we don't have to pay these fee's we aren't supposed to?
