The short version

An air traffic communications outage can lead the FAA to hold departing flights while officials investigate safety concerns. ²
During the nationwide stop on November 13, 2026, planes already in the air were allowed to land, according to reporting on the FAA action. ⁴
Delays can continue after a restriction because planes and crews may not be where their next flights are scheduled to begin. ⁵
Passengers can check current flight information with their airline; the supplied reports do not establish how long the disruption lasted or its final cause. ²⁵

How can a communications outage affect flights?

Air traffic control depends on communication to coordinate aircraft. When problems affect control facilities, officials may pause departures while technicians investigate and assess safety. On November 13, 2026, the FAA reported communication problems affecting multiple air traffic control centers and issued a nationwide ground stop. ²

Reports also described possible effects on radar capabilities and air traffic control frequencies, but the supplied material does not provide a full technical explanation of the outage. ²⁴

What does a ground stop require airlines to do?

A ground stop is an instruction for specified aircraft to stay at their departure points. It may cover one airport or a wider area. In the November 13 event, the FAA ordered a nationwide stop on departing traffic and said it would remain in effect until further notice. ²³⁵

That does not necessarily mean every flight is canceled. It means covered departures cannot proceed while the instruction applies; airlines may delay or cancel individual services as the situation develops. ²⁵

Are planes already flying allowed to land?

Yes, reporting on the November 13 ground stop said aircraft already in the air were allowed to land. The order was directed at departures. ⁴

The FAA said inbound international flights would be handled case by case. The sources do not describe the decision for every arriving flight. ²

Why can delays continue after departures resume?

A pause can affect later flights, too. Aircraft and crew members may be unable to reach the airports where they are expected for their next scheduled trips, which can cause further delays or cancellations. ⁵

Reports about the November 13 incident described delays and passengers being taken off aircraft, but the supplied sources do not establish the final number of affected flights or the total duration of disruption. ¹²

What can passengers check during an outage?

Check your airline's flight status and messages for the latest information about your specific departure. Schedules may change as officials investigate and airlines respond; the sources do not give a confirmed timeline that applies to every flight.

For a missed connection or a changed itinerary, contact the airline handling your booking. Follow current instructions from airline staff and official updates rather than relying on an earlier estimated departure time.

What we don't know yet

The supplied reports do not establish the outage's final cause or full technical details.
They do not give a confirmed duration for the ground stop or when all affected departures returned to normal.
The total number of affected flights and passengers is not established in the supplied material.
