Commuters at the Bengaluru International Airport  had their first brush with flight delays and diversions this winter due to fog. Thick fog, which lasted till 6.30 am, resulted in the delay of almost 13 flights, while two flights were diverted.Airport officials said the flights were delayed for 5 to 15 minutes and normal operations resumed after 6.30 am.

Officials said that an Etihad airline flight was diverted to Colombo. Similarly, an Air India flight bound to Bangalore from Goa was diverted to Chennai.Airline officials said that the flight was scheduled to land at 5.45 am, but was diverted to Chennai and had to halt there until 6 am.The fog-related delay at the BIA normally has a cascading effect on flight schedules as there are huge backlogs of aircraft, both on ground and in air.Normally, the fog that occurs at the BIA, known as ‘radiation fog,’ is anticipated from November 15 to February 15, between 3 am and 8.30 am.
