On Sunday night, IndiGo issued a travel advisory, alerting passengers to potential delays due to low visibility caused by fog. The airline advised travellers to allow extra time for their journey and to check flight statuses before heading to the airport. Delhi International Airport Ltd (DIAL) confirmed that the airport was operating under low visibility procedures, but flight operations remained normal as of 10:14 pm on Sunday. The foggy conditions were further worsened by high pollution levels, making the already poor air quality in Delhi even more hazardous. The Commission for Air Quality Management (CAQM) triggered Stage IV of the Graded Response Action Plan (GRAP) due to the deteriorating air quality, with the city’s Air Quality Index (AQI) surpassing the 450 mark, categorising it as a "severe plus."
