Terminal 1 at arrival and departure both times a revolting experience. Barely made it to my flight after needing 4.5 hours from Paris Gare du Nord to my departure gate - Schenghen flight. The so-called architecture of this airport is an insult to those passengers that have to use this disgrace of a labyrinth that should be demolished and rebuilt from scratch. The tiny and crowded walkways the redundant direction displays contradicting each other the feeling of being buried alive in a nuclear shelter even the lack of shops! Staff was outrageous at best witnessed several members of check-in the staff snapping at confused Asian tourists. Once you get through the security controls be ready to stand in line for up to 20 minutes for a bottle of overpriced water at the single bar. Need to use the restroom? Too bad there's a flight boarding in front of it- the gate has been strategically located right between the exit of the security controls and the beginning of the queue with only a few dozens of chairs available. I will never use this airport again.
