The Bangalore International Airport Limited (BAL), which runs Kempegowda International Airport (KIA), has issued an important alert. All IndiGo flights from KIA are cancelled until 10:59 p.m. on December 5. "Passengers are requested to note that IndiGo flights from KIA to Mumbai and Delhi stand cancelled until 11:59 p.m. on December 5," the official advisory says. For flights to other destinations, passengers must check with IndiGo directly before leaving for KIA. BIAL teams are working closely with IndiGo and other partners to reduce passenger trouble during this disruption. At the airport, some IndiGo passengers protested loudly inside the terminal, expressing their frustration. This is not a new problem. On Friday morning, BIAL reported that at least 102 IndiGo flights were cancelled at KIA, marking four days of constant flight disruptions.
