> Well, yeah, but what is the problem with that?

Because Airlines seem to be the intended target and not the tourist. I would imagine they would have instituted an airport fee if the tourist was the target.

This could cause a drop in tourist dollars but maybe that's the goal. It seems Europe in general is wary of tourists. Spain has gone so far as to discourage tourism to Barcelona by restricting any new hotels or tourist accommodations. France may be following their lead and taxing Airlines instead, creating less across the whole country instead of a particular city.
