Industry insiders say that the airline's operations were also impacted due to shortage of crew on account of flight and duty time limitation (FDTL), which mandates a maximum of eight hours.
Since delays or diversions led to a cascading impact throughout airline's network, some estimates put the number of flights cancelled during the weekend at around 50.
"Due to a severe hailstorm in north India on Friday, February 7, 2019, 11 IndiGo flights were diverted. Consequently, this disrupted operations across our network the following day," the company said in a statement.
"As part of recovering our schedule, positioning of the crew and aircraft had to be readjusted. As a result, a number of flights were cancelled."
At present, IndiGo, with its fleet of over 200 aircraft, offers over 1,300 daily flights and connects 52 domestic and 16 international destinations.
