North India carries 30 percent of air passengers but fog still disrupts every winter

Fog delays flights, even as major upgrades spread

The Northern Region of the Airports Authority of India handles around 30% of India’s air passenger traffic, but winter fog remains a persistent operational threat, disrupting flight schedules. The AAI says multiple airport infrastructure projects are underway across northern India. Alongside expansion, the authority is also pursuing environmental targets, including carbon neutrality by 2030.
