It was horrible to travel out of Copenhagen Saturday 20. of June 2009 due to low manning and/or low capacity to handle the amount of passengers. Arriving at the airport more than 1 hour and 20 minutes prior to the scheduled flight-time of the plane to London should be sufficient enough. First the automatic check-in facilities did not recognize my reservation number even though there had been no changes in the reservation since the purchase 10 days prior. I and a handfull of other passengers were sent to a line for passengers with problems using the check-in machines. This line was handled by one person only and 25 minutes prior to departure after being in line for 40 minutes we finally convinced an employee to check us in separately and bypass the line. We were met by another big line at the security control but just managed to get on the airplane by running through the entire terminal. The staff appeared to be in a bad mood no wonder and one member even critizised us for arriving at the airport too late. When I arrived in North America 18 hours later the local baggage service informed me that my suitcase had not left Copenhagen Airport yet. Rail transportation to the airport works excellent though. I would like to have reviewed other aspects of the airport but I did not have the time to notice that.
