Flights to Kolkata from Delhi and Mumbai to operate three times in a week

Flights to West Bengal will be operating thrice weekly from Mumbai and Delhi, according to latest reports. The West Bengal Home Secretary has written to the Ministry of Civil Aviation, Government of India, notifying of the operation of flights on Mumbai-Kolkata and Delhi-Kolkata routes, thrice per week.
According to the latest rulesl flights will operate on Mondays, Wednesdays, and Fridays from Delhi and Mumbai. The flights are already operating as of today, and the rule came into effect from January 5, 2022.

As of now the rule stands, but this could change as and when the situation changes. Currently, COVID cases are on the rise in the state of West Bengal, much like it is in most parts of the country. The state reported 14022 new cases on Wednesday, which is 4949 more than what it was a day earlier. The state government is currently acting with caution, but is said to be sensitive towards the inconvenience caused to passengers.
The state government in West Bengal had earlier announced restrictions on flights from Mumbai and Delhi. This is due to the high rate of positivity caused by the new Omicron variant. The state is currently under a partial lockdown, which means that markets, shopping malls, bars, and restaurants are operating at 50 percent capacity. All such establishments close at 10 pm sharp. Moreover, entertainment parks, and zoos are shut. These rules will continue until January 15.

The West Bengal government had also banned all flights coming in from the United Kingdom into the state from January 3 onwards. All international passengers are required to get a COVID-19 test upon arrival at the airport.
