What is the worst airport
To me that would be Philadelphia:
We were on landing approach coming from Germany, when only seconds before touchdown the Pilot accellerated and pulled up very steep. After a few seconds he announced that there was an airplaine on our runway. After another round he landed. We proceeded to immigration, being very nervous as we may miss the connection flight due to the delay. Immigration went smooth. We then had to check our luggage for the connection flight. There was an enourmous line for that, that took us 40 minutes to pass.
Now we were almost certain to miss the connection but we decided to make a run for it. We came around a corner and noticed this section was closed due to reconstruction. So we had to leave the security area and exit the airport. Run around a corner and come back in. Of course we had to go through security again. What a bummer. When we ran towards our gate, we quickly stopped at the monitors, found out the flight had been assigned to another gate, turned around and ran like hell. We ran right to the gate, gave the lady our tickets and ran into the plane. The doors shut behind us the moment we were in and the airplane took off almost empty, as noone else made the connection.
Best Airport: There is no such thing.
