The Federal Aviation Administration (FAA) ordered on Tuesday that all flights operated by JetBlue be grounded across the United States.
According to the FAA advisory, the ground stop was implemented at the request of the airline itself. The reason for the request was not stated in the notice, and further information was not immediately available.
Initial reports by the Daily Mail claimed that the carrier's nationwide ground stop appeared to have been caused by a major connectivity issue with IT Services at the airline's headquarters in New York City.
