Family member and I were flying from America to Germany, having connecting flight to Czech. Our first flight departed few hours later, and during the flight Condor cancelled our connecting flight because we wouldnt have enough time to transfer. We actually sprinted across the airport and made it to an open gate, but our tickets wouldnt work, all while watching people from other flights board normally.
We were directed to their kiosk, where after 2 hours of waiting and 2 hours of explaining/negotiating we were rebooked on a flight next day, with "all our airport and contract accomodations are full, find your own one, condor will refund". Spent the night in €700/night hotel (fourth I called, first to actually had rooms).
Afterwards we sent all info/invoices throug mail. First reply: we refund your expenses, but not flight compensation ($600 per person), because the delay was not our fault, the delay was less than 4(6?) hours, and (despite the flight landing in EU, which is all it takes for EU legislation to apply) the flight is not covered by EU legislation, because it originated from outside EU.
Sent extempt from law saying they have to pay us, or we will involve layers. Next email said they will issue full requested refund (which they did).
So, apart from having to threaten with legal action and having to know our rights trough Condor lies, pretty good outcome.
