Passed through the CDG airport in Paris recently both ways while travelling from Toronto-Bucharest and back. Both ways we were debarked form the air-plane (Air France) on the tarmac and transported by bus to the terminal having to go through the security check although we were not changing the terminal towards our final destination. Coming back from Bucharest we had 2hrs to wait until our flight to Toronto. Once out of the bus bringing us from the aircraft to the terminal once they checked our next flight schedule we were directed to a line towards the security check that has not advanced for the next 90 mins. We were held standing like sardines in a can together with other hundreds of passengers for 90 mins without any explanation. After several attempts to find out what is going on we were finally told that we had to wait here in this very crowded line standing up until all the passengers having less then two hours between their flights are processed first through the security check. In any other airport in the world I travelled through the security check is performed on a first come first served bases and passengers that are either late or have short time between flights are brought to the front of the line and nobody complains about. We barely made it to our flight to Toronto extremely tired and aggravated. I will avoid at all cost ever going through this extremely poorly managed airport.
