As dense winter fog continues to blanket Delhi and large parts of northern India, major airlines have issued travel advisories warning passengers of possible disruptions. Airlines including IndiGo, Air India and SpiceJet have cautioned possible delays and cancellations at Delhi airport, especially during early morning hours.
Travellers have been advised to stay alert, check flight status before leaving for the airport, and be prepared for delays or schedule changes as weather conditions remain unpredictable.
IndiGo flags early morning disruptions due to fog
In its advisory shared on X (formerly Twitter) IndiGo said that seasonal fog across Delhi and other parts of northern India is reducing visibility and affecting flight movements. The airline warned passengers travelling during early hours that they may face delays or revised timings and urged them to check the latest updates before starting their journey.
“Early morning fog in Delhi and across parts of northern India is affecting visibility and impacting flight operations. We seek your understanding, as this is a seasonal occurrence, and flight movements are being managed accordingly to ensure safe and orderly operations,” the advisory said.
