Most of the flights had to be diverted, as the pilots were not trained to operate flights in low visibility conditions, the sources claimed. As many as 13 flights of IndiGo were diverted while 10 flights each of Air India and SpiceJet were diverted during the period. Among others, 5 flights of Vistara, 3 flights of Akasa Air and 2 flights of Alliance Air were diverted at the Delhi airport.
