US ground stop: all aircraft grounded after communications failure
Every aircraft in the United States is being kept on the ground right now because a communication system has failed, according to first reports.

Nothing is flying in the United States at the moment. All aircraft have to stay on the ground, and the reason is a failed communication system.
That is the core of what is known so far. The ground stop covers the whole country, so airports are effectively closed to departures while the outage lasts. For travellers, that means delays and waiting at the gate, or in the terminal, with no clear end time yet.
Why are all US flights grounded?
The stated cause is the outage of a communication system. Which system it is, what broke it and how long repairs will take has not been made clear in the information available. Those details are not confirmed, so it is too early to say whether this is a technical fault or something else.
What should travellers do?
If you have a flight to, from or within the US, check your airline's app or website for the status of your flight before leaving for the airport. Airlines will be the first to know when departures can resume.
This story is developing, and the numbers of affected flights and airports have not been given.
