NEW YORK CITY — American Airlines flights out of JFK, LaGuarida, Newark and the rest of the country's airports were experiencing delays and cancellations after being grounded nationwide for several hours when the company experienced problems with its reservation and booking system.
The company said in a Facebook post that its systems had been fully restored by about 4:30 p.m. but to expect delays through the rest of the day.
"We expect our operation to run normally with only a small number of flight cancellations expected tomorrow," the airline posted Tuesday on its Twitter feed.
The FAA had issued the order to ground all American flights after 2 p.m. amid heightened security in many cities after the bombings at the Boston Marathon.
"American's network system is experiencing intermittent outages," AA spokesperson Mary Frances Fagan said in a statement. "At this time, we are in a system-wide ground stop that will last until 4:00pm CST (5 p.m ET)."
"Our reservation & booking tool Sabre is offline," the airline posted earlier Tuesday. "We're working to resolve as quickly as we can."
The airline later tweeted that all planes nationwide would be grounded until 5 p.m. Eastern Time as they worked to resolve the issue.
American emphasized that it saw no evidence connecting the technical outage with the tragic events in Boston.
