Delhi woke up to foggy conditions on Tuesday with air quality slipping back into the very poor category, prompting airline advisories, flight disruptions, a day after heated political confrontation over pollution in the Assembly. According to IndiGo, the low visibility has affected flight schedules over Delhi, Amritsar, Bhopal, Chandigarh, Guwahati, Varanasi, Ranchi, and Hindon (Airport).
Foggy Mornings Disrupt Air Travel Across Cities
Parts of Delhi woke up to a thin layer of fog as severe cold conditions continued to grip the region. Reduced visibility early in the morning affected flight operations not just in the capital but across several northern and eastern cities. Airlines cautioned passengers about potential delays and cancellations as weather conditions remained unpredictable.
At around 6 am, Delhi Airport also issued a passenger advisory, urging travelers to check real-time winter updates and plan their journeys cautiously due to low visibility.

Air Quality Slips Again After Brief Respite
While fog dominated the skyline, air pollution remained a major concern. According to the Central Pollution Control Board (CPCB), Delhi’s overall Air Quality Index (AQI) was reported at 180, placing it in the moderate category. However, localized readings painted a more alarming picture, with AQI-IN levels touching 366, classified as very harmful. PM2.5 and PM10 concentrations were recorded at 208 and 295 respectively.
On Monday, January 5, Delhi’s AQI slipped back into the very poor category after showing signs of improvement over the weekend, underscoring the fragile nature of air quality gains during winter.
Pollution Debate Spills Into Assembly
The worsening air quality also triggered political turbulence during the opening day of the Delhi Assembly’s winter session. Lieutenant Governor VK Saxena’s address was interrupted by several AAP MLAs, including Sanjeev Jha, Kuldeep Kumar, and Jarnail Singh, who attempted to raise the issue of air pollution. Speaker Vijender Gupta ordered their removal from the House.
Opposition leader Atishi, along with other AAP legislators wearing industrial-grade masks, staged a protest within the Assembly complex. Following the address, PWD Minister Parvesh Sahib Singh moved a resolution to suspend four AAP lawmakers for the remainder of the session, which was passed by the House.
