I and those with me, five people in total, could not enter the plane under the pretext that the board was closed. We were delayed for five minutes. Due to an accident in the street, we stood for three hours in the street. In the end, they did not cooperate with us. We are five people.. on the same flight.. Now we stayed in a hotel.. 2 nights. We bought tickets again to go back
