The air link between Calcutta and six other Indian cities, including Delhi and Mumbai, will resume on Tuesday with 36 flights on each day, officials of the airport and airlines said.

Flights from these cities were suspended on July 6 as a precaution against Covid-19. The state government had a few days ago informed the civil aviation ministry that flights could operate from Delhi, Mumbai, Chennai, Pune, Ahmedabad and Nagpur to Calcutta three days a week from September 1.

Calcutta airport sources said 14 flights would operate from Delhi, eight from Mumbai, six from Chennai, four from Pune, three from Ahmedabad and one from Nagpur.

“We have almost full occupancy for the first few days,” said an official of a private airline.

Initially, the state government had wanted to ban flights from eight cities, including Surat.

SpiceJet was operating the lone flight between Calcutta and Surat. Though Surat was not finally included on the list, SpiceJet stopped the flight. Airport sources said SpiceJet would resume the Surat flight.

Metro has reported that flights from the six cities to Calcutta will operate on Tuesdays, Thursdays and Sundays from September 1 to 13. From September 14, they will operate on Mondays, Wednesdays and Fridays.

The dates have been fixed keeping in mind the three lockdown days chief minister Mamata Banerjee has announced — September 7 (Monday), 11 (Friday) and 12 (Saturday).

Before the ban, 25-odd flights would operate from these six cities to Calcutta every day.

Many passengers were taking flights through other cities such as Guwahati and Lucknow from Delhi and Mumbai to reach Calcutta.
