Hi all,
Note that Avis has started adding a no-show fee indication for rentals booked on some of the European sites (for example, Switzerland). (And yes, this includes a rental in the US booked from Switzerland.)
So yes, they are moving in that direction, and I'm sure it will come to the US at some point.
Now, as a disclaimer, I've had the notice on my rentals, but as I've not been a no-show yet, can't tell if they apply it.
Cheers,
GenevaFlyer
