Booked a flight from Amsterdam to Leipzig and back. When I arrived at Amsterdam airport a delay of 3hrs was announced. No-one behind the counter but I was advised by the airport personnel that staff of another counter would represent Darwin. Went there but no-one present. Was referred to yet another counter yet another company yet another person. Having found this person didn't provide any more information. After 3hrs the counter opened and we could check-in with the confirmation that the +3h flight would be 100% on time and arrive in Leipzig without any further delay. While waiting for the flight I received an announcement that the flight was delayed by another 5hrs! As this meant that I missed the lecture I was to give in Leiden I gave up and went home. Was reimbursed by Darwin for the flight (no excuses of course) but still had to pay for hotel and train. That wasn't an isolated experience it seems as other passengers had more reports about 5-36hrs delays.
