American Airlines suffered a widespread outage with its flight information computer system, authorities with two affected airports told CNN. In a statement to CNN, American Airlines said a “technology issue” was “affecting connectivity” for some of its systems.

American Airlines flights have resumed after a system outage grounded flights. Multiple reports on social media said planes were unable to take off because of technical problems. According to reports on X, one pilot said he couldn't sign the maintenance form to be cleared for takeoff because his computer was not working.

A systems outage temporarily grounded some planes on Friday, causing headaches for both crew and passengers around the United States.
