IndiGo prepares ground team, advises early planning
IndiGo said its airport teams are fully prepared and working in close coordination to manage schedules, support customers and ensure smooth operations despite challenging weather conditions. The airline has advised passengers to travel early in the day to plan their journeys with additional buffer time and to check the latest flight status on its website or mobile application before heading to the airport.
The advisory also warned that fog could affect road traffic and could lead to slow movement and longer times for commuters. IndiGo thanked customers for their patience and continued trust, underlining that visibility is expected to improve as the day progresses gradually.
The airline advisory comes amid widespread fog conditions that have already started affecting flight operations in the national capital and surrounding regions.
Dense fog disrupts air traffic
Earlier on Tuesday morning, Indira Gandhi International Airport (IGI) in Delhi also issued its own fog advisory, informing passengers of possible disruptions in departures and arrivals due to reduced visibility. In a post shared around 6:06 am, Delhi Airport stated that flight operations were “steadily recovering” but cautioned that certain services could continue to face delays.
The airport advisor urged travellers to stay in touch with their respective airlines for accurate and timely updates on flight schedules. It also mentioned that additional ground staff had been deployed across terminals to support passengers and manage operations during the foggy conditions.
The situation has been further complicated by deteriorating air quality in the national capital. As per the real-time AQI data, Delhi’s overall Air Quality Index stood at 340 around 7 am on Wednesday, placing it in the ‘hazardous’ category. Dense fog combined with hazardous pollution levels has significantly reduced visibility during early morning hours.
