Dallas-Fort Worth International Airport (KXAS)
DALLAS (KXAS) -- An outage in the main reservations system of American Airlines has been repaired.
According to a spokeswoman for the airline, Stacey Frantz, the system was fixed around 4:30 Tuesday afternoon. However, flight delays and cancellations are expected throughout the rest of the day, Frantz said.
Tracking service FlightAware reported that American had canceled over 700 flights, and delayed 765 as of Tuesday mid-afternoon.
Customers continue to wait in long lines at airports.
Earlier on Tuesday, American Airlines said its reservation system was down and that all flights were being grounded until 5 p.m. ET while they worked to get it running again.
After initially saying their reservation and booking tool, Sabre, was offline, the airline later clarified and said they were unable to access their reservations system and that the issue was not with Sabre.
"We're working to resolve the issue as quickly as we can. We apologize to our customers for any inconvenience," said Mary Frances Fagan, American Airlines spokesperson.
The outage caused delays nationwide as it affected passenger check-in.
American Airlines arrivals were on time 89 percent of the time, while departures were 91 percent on time according to FlightStats.com at the time the system went down.
The beleaguered company is emerging from bankruptcy protection and is about to file its reorganization plan as it merges with U.S. Airways.
