For West Bengal, the reluctance is primarily due to Cyclone Amphan.
The state governments of Maharashtra and West Bengal are yet to give their approval for flights resumption for their respective states, sources said, adding that the Union government continues to engage with states on the "evolving situation."
"We are yet to receive permission for flights from West Bengal and Maharashtra," an industry insider told CNBC-TV18.
Sources said the aviation ministry is constantly in touch with state government officials regarding flights resumption and while the resistance is on "expected lines," efforts are ongoing for a graded resumption of flights from May 25.
Its extremely ill-advised to reopen airports in red zone. Mere thermal scanning of passengers inadequate w/o swabs. Impossible to have autos/cabs/buses ply in current circumstances. Adding positive passenger will add Covid stress to red zone.#MaharashtraGovtCares

Frequently Asked Questions
A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.
There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.
Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
Confused about whether flights will be able to operate from Maharashtra and West Bengal with bookings already done, airlines too are awaiting clarity from the government, sources added.
The Centre has been working with the assumption that the virus is here to stay for some time, and hence, it does not make sense to resume flights from June 1 instead of May 25. But some states want to delay flights resumption as much as possible, sources said.
A meeting has been scheduled between the Union aviation ministry and the airlines today and clarity is expected to emerge on the matter after that.
As far as quarantine is concerned, several states like Punjab have mandated 14-day home quarantine for all returnees via Air and while some like Karnataka have mandated 7-day institutional quarantine and 7-day home quarantine for those coming from high prevalence states such as Maharashtra, Rajasthan, Delhi, Madhya Pradesh, Gujarat and Tamil Nadu.
The Tamil Nadu government has said that it would rather that flights from the state did not resume on May 25, but added it will comply with the decision taken by the Centre as flight resumption cannot be a unilateral decision.
Tamil Nadu is open to flight departures, but officials said that arrivals could be problematic for lack of quarantine facilities. The government is particular about quarantining incoming air passengers for 14 days, should the infrastructure allow for it.Click here for Moneycontrol’s full coverage of the novel coronavirus pandemic
