I was in Nantes Atlantique Airport just before Christmas. I was in transit from Amsterdam going to Bordeaux. I was surprised that I had to go out and re-enter the place via security. There is no transit area. Thanks to the all glass design I saw that there was absolutely nothing to do once you passed security so I only went when it was boarding time. There are different terminal and loads of shops which is good but you always get the smell of the smoking people outside into the terminals because of the wind and I found it very unpleasant. The toilets were not particularly at 2pm already so it gives a CDG dejá vu feeling. It could be a great airport with some improvements.
