A 55-minute transfer window at Zurich Airport is exceptionally tight and depends entirely on your exact gate combination and ticket routing. If both arriving and departing flights utilize the same terminal zone without requiring a change of concourses or secondary passport controls, an agile traveler can make it. Nevertheless, travel experts strongly advise booking longer layovers, because a 55-minute window provides zero cushion for unexpected flight delays or congestion at transfer security checkpoints.
