New Delhi, Jan 9 (UNI) Low visibility and dense fog disrupted flight operations across several parts of India on Friday morning, leading to delays and diversions.
IndiGo flight 6E-2334 from Delhi to Varanasi was diverted to Lucknow due to poor visibility caused by dense fog. Several other flights scheduled to operate to and from Varanasi were also diverted.
Airlines issued travel advisories to minimise inconvenience to passengers. IndiGo, in a travel advisory issued on Friday morning, warned of possible disruptions due to low visibility and fog over Assam and Tripura.
The advisory stated, “Low visibility and fog over Dibrugarh and Agartala may impact flight schedules. We are closely monitoring the weather and are doing our best to get you where you need to be safely and smoothly. We request that you stay updated on your flight status via our website or app.”
In a separate advisory, the airline said dense fog in Varanasi continued to affect visibility, impacting flights operating to and from the city. “As conditions evolve, some services may experience delays, and a few may need to be cancelled depending on clearance and operational feasibility,” IndiGo said in a post on X.
Meanwhile, the Directorate General of Civil Aviation (DGCA) has designated a ‘fog window’ from December 10 to February 10, a period during which dense fog typically affects large parts of north India.
As per DGCA norms, flight operations during such conditions are largely conducted using CAT-III B–compliant aircraft. Category III is an advanced navigation system that enables aircraft to land safely in extremely low-visibility conditions.
