The US Federal Aviation Administration has ordered a nationwide ground stop for all departing flights until further notice, citing extraordinary circumstances and reasons for safety. The decision was made due to communication issues affecting all air route traffic control centres. The FAA had earlier halted traffic in Chicago due to air traffic control problems.
International flights are being handled on a case-by-case basis. The FAA is currently investigating the cause of the communication problems. The ground stop was announced shortly after the FAA halted traffic in Chicago. The situation is ongoing, and the FAA has not provided a timeline for when flights may resume.
The US Transportation Secretary, Sean Duffy, has confirmed that the communication issues are widespread and are the primary reason for the grounding. The FAA has not yet resolved the problems affecting air traffic control centres.
