United Airlines temporarily suspended flights to New Delhi on Friday on concerns over air quality.
"We are monitoring advisories as the region remains under a public health emergency, and are coordinating with respective government agencies," CNN Money quoted a representative for the airline as saying.
The airline allowed customers traveling to Delhi from 9 November through 13 November to re-book a comparable ticket for 18 November or before, with no additional cost.
The capital woke to a white haze on Tuesday, 7 November as temperatures dropped and the smog became apparent. The Indian Medical Association has declared the smog a “public health emergency”.
