Every day thousands of people change currency at Spanish airports, where it is very comfortable, but not cheap at all!
Almost all of these travelers have something in common: leaving travel money for last minute and not caring much about the exchange rate applied to them at the airport.
In exchange for travelers, the airport authority requires the exchange supplier to participate in the revenues from all currency operations.
This makes the currency exchange at airports a lot more expensive than at high street level. Therefore, the airport should be our last currency exchange option in Spain.
