Hi,

I'm preparing for my first trip to Europe this summer, so I'm trying to figure out how things works...

I renting a car from Belgium and dropping it in Zurich

I don't quite get the reasoning behind "One way fee"
I understand the fee for dropping at a different location but not how
the amount is calculated....

If I rent the car for 7 days I get a daily charge of 97$
If I only change the number of rent days to 4, I get a daily charge of 170$

Why would this charge even change if the drop location does not change???
