Fliers urged to check flight schedule

Citing the weather department's dense fog warning in Delhi, several airlines like Air India, IndiGo and SpiceJet warned of flight disruptions on Friday.

“Customers are advised to check their flight status before heading to the airport and allow extra time for travel, as low visibility may lead to slower traffic on the roads,” a part of IndiGo's tweet read. The airline witnessed mass cancellations earlier this month, disrupting travel plans of thousands of passengers.

SpiceJet also issued a similar advisory for its passengers, asking them to keep a check on their flight status.

Air India also informed passengers about their ‘FogCare’ initiative, through which they can receive advance alerts on their registered phone numbers, with the option to change their flights without any additional payment.

Visuals from the Delhi airport this morning showed that some flights had been cancelled.

The Delhi airport also said that some flights have been disrupted as operations are currently being conducted under CAT III conditions due to low visibility. The development came a day after 27 flights were cancelled in Delhi due to low visibility and thick fog conditions.
