 "2 days after global outage: Airlines play catch-up with flight schedule")
The Indian aviation sector continued to take a hit from the global Microsoft outage two days ago, with heavy rains in Mumbai aggravating the situation.
About 1,000 flights were behind schedule on Sunday at three of the busiest Indian airports, with Mumbai airport recording 18 cancellations, according to people in the know.
Live flight tracker flightradar24 showed at least 417 flights (305 departures and 112 arrivals) faced delays on Sunday at the Delhi International Airport. The country's busiest airport handles about 1,260 daily scheduled flights.
The Mumbai airport, meanwhile, had to suspend its runway operations twice on Sunday — for eight minutes between 12.12 PM and 12.20 PM, and for 15 minutes between 1 PM and 1.15 PM — due to low visibility amid adverse weather conditions, sources said. About 18 flights to and from the financial capital were cancelled, with 12 from IndiGo, followed by four from Air India and two from Vistara. The Mumbai airport, which is India's second busiest, handles about 870 daily scheduled flights. At least 430 flights (272 departures and 158 arrivals) reported delays on Sunday at Mumbai airport, according to flightradar24.
"Heavy rains in Mumbai are affecting flight operations and resulting in cancellation and diversion of some of our flights," Air India said on X, adding that it was offering full refunds, or a one-time complimentary rescheduling options to affected passengers.
