American Airlines, United and Delta have asked the FAA for global ground stop on all flights, according to an alert from the FAA on Friday morning.
The FAA is telling air traffic controllers to tell airborne pilots that airlines are currently experiencing communication issues.
Meanwhile, flights in the air will stay in the air, but no American, United or Delta flights will take off.
It is unclear how widespread the issue is but Melbourne Airport in Australia has also said they are “experiencing a global technology issue” which is impacting their check-in procedures.
No further details have been released.
