Flight cancellations: Airport chaos angers Indians as fog hits travel

India's aviation regulator has issued an advisory to airlines after dozens of people took to social media to complain about flight delays and cancellations.

The regulator has asked airlines to cancel flights "sufficiently in advance" and inform passengers about delays in real time.

Airlines have blamed the cascading effect of fog in Delhi for the chaos.

But furious passengers have accused airlines and airports of inadequate communication.

A man was arrested and later released on bail after he was accused of assaulting a co-pilot of IndiGo airlines. The man's flight on Sunday had been delayed for more than 10 hours. A viral video showed the passenger lunging at the co-pilot as he made an announcement on the plane.

Another video showed passengers eating food while sitting on the tarmac at the Mumbai airport, where their flight from Goa to Delhi had been diverted after hours of delay.

Hundreds of domestic flights have been delayed since Sunday after a thick fog engulfed Delhi, which is home to one of India's busiest airports. It is also the main hub for major airlines such as IndiGo and Air India.

While fog is an annual occurrence, reports say the situation is worse this year at the Delhi airport due to other factors including parking shortages due to grounded aircraft and a runway being shut for maintenance.

The disruption, which intensified on Sunday, had a cascading effect on Monday and is likely to continue on Tuesday as well.

The weather department has predicted two more days of heavy fog in Delhi and other northern cities. Several trains have also been delayed.

Since Sunday, several passengers had tagged federal aviation minister Jyotiraditya Scindia and various airlines on X (formerly Twitter) to complain about flight
