Flight operations at the city airport were severely affected on Wednesday due to the closure of main runway, coupled with water-logging at terminal 1-C and power cut.
There was a delay of more than one hour across flights at Mumbai airport due to the closure of runway for over an hour, an airport source said here.
At the top of it, there was power cut as well as water-logging of newly constructed terminal 1-C which further led to congestion at the airport, the source said.
The Mumbai International Airport Ltd (MIAL) said that the main runway 09x27 was closed for 50 minutes (0810 hours to 0900 hours) to clear glass pieces of runway edge light which were broken by a departing aircraft.
?Due to the closure, there was a long queue of aircraft at the runway awaiting clearance from the ATC,? source said.
The source also said that following rains last night, there was water-logging at terminal 1-C leading to the closure of the area.
