My experience at CDG was absolutely terrible. I was in Terminal 2 which belongs to Air France. The check-in lines were horrifically long. After you endured check-in you were faced with mayhem at security. The terminal had created three different security lines- one for first class one for Asian flights and one for flights to the US. Of course barely anyone went through the First Class line. Then there were only about 5 flights in the Asian line and about 3 working scanning machines. For the US line there were roughly 12 flights assigned to this line and only one working machine (which actually stopped working by the time I got to it). The line had no rhyme or reason- employees would open up sections of the line to let people into another seemingly faster line only to let them back into the original line when it wasn't actually faster. So I spent about 2.5hrs in that security line. When I got to the scanning machine there were no signs to inform you that every single electronic device had to be taken out of your bag so the machine would go off for every bag that passed through. The walk-through scanner didn't work either. My plane was delayed 1hr because it had to wait on all of the people who were stuck in that horrific security line. It was utterly ridiculous. Nightmarish. I am so discouraged from going back to Paris. Definitely won't be leaving from CDG again. Don't make the same mistake. And if you must get there 6hrs in advance.
