The Federal Aviation Administration has received several requests from federally-funded airports, asking to close and restrict airport access, according to the agency.
The FAA generally does not allow closure of airports that receive federal funds and any request must be approved by the agency.
The agency is reviewing requests from Puerto Rico and Tangier, Virginia, an island town located in the Chesapeake Bay.
Earlier Thursday, CNN reported that Puerto Rico's governor, Wanda Vazquez Garced, wanted to redirect all flights to enter through the international airport to centralize screenings. "It's severe but I think we can" work with the FAA on this, she said.
According to the FAA, Vázquez and the Puerto Rico Ports Authority submitted proposals to restrict airport access and close airports in Puerto Rico. Additionally, the town of Tangier, in Virginia, wants FAA approval to close Tangier Island Airport.
