If you are travelling from Delhi today, be ready to face some disruption. Several flights have been delayed due to low visibility in the national capital. With the air quality bordering the 'severe plus' category, a public health emergency has been declared in Delhi on Friday.

In a tweet Delhi Airport mentioned, "Due to low visibility, flight operations at Delhi Airport are affected. All CAT-II compliant pilots are able to operate." All the travellers are asked to check with the airline for the latest flight updates.

India's biggest airline IndiGo advises its passengers to keep some extra travel time in hand due to rainfall in several parts of National Capital Region (NCR).

More than 30 flights were diverted to nearby airports due to the poor visibility in Delhi. "Flight UK810 from Bangalore to Delhi has been diverted to Amritsar," Vistara wrote on Twitter.

Airlines are forced to reschedule many flights in the wake of rising pollution in Delhi. Poor visibility or bad weather is the main reason behind this disruption, stated most of the airlines. Air India asked its customers to check flight status before reaching the airport.

"Due to poor visibility at Delhi (DEL), all departures/arrivals and their consequential flights might get affected," tweeted budget carrier SpiceJet.

Delhi's Indira Gandhi International Airport is one of the busiest airports in the country which handles more than 500 arrivals and departures daily.

To tackle the severe air pollution in the capital, Delhi government decided to reintroduce odd-even scheme from November 4-15.
