KOLKATA: Unseasonal fog at Kolkata airport on Monday morning led to one of the worst disruptions in recent years with visibility plunging to under 25 metres that brought operations to a halt for nearly four hours.
Five flights were diverted and scores of flights that were to depart in the early morning were delayed. The cascading effect of these delays were felt all day, affecting the on-time performance of many flights heading to Kolkata or taking off from the city.
