I have flights with airberlin from Vernice to Zurich and the stopover is at Dusseldorf. Both flights are short haul and the transit time is 55 minutes. Can anyone assist me if 55 minutes are sufficient for me to travel to the boarding gate? I have checked bag as well, so will it transfer to the connecting flight? Last question is when I arrive at Dusseldorf, how do I go about to make my way to the connecting flight?
