Traveled 2 times with them from Hamburg to Berlin SXF airport, both times with a terrible outcome. First time the bus was late by 30 minutes, and arriving waaaay past the scheduled time, almost missed my flight arriving the very last minute at the gate. 2nd time, and the most terrible experience, the driver took a national road instead of the autobahn, the trip was supposed to be around 4 hours long. The driver was extremely slow, and once his working hours ended (~4 hours) he decided to take a 45 minute break (or until another driver arrives) once entering the city of Berlin (we were supposed to have another 1 and a half hour drive to the airport from that place). Risking to lose the flight again, we had to take the taxi for which we had to pay 60 euros. That didn't bother the management, no refund for the taxi ticket, no refund for the bus ticket. An absolute joke of a company with the most incompetent and ignorant drivers and management. PAY EXTRA AND TAKE THE TRAIN
