(Reuters) -U.S. flights were delayed and airports told passengers to
check with their airlines for updates on Wednesday as the Federal
Aviation Administration (FAA) scrambled to fix a system outage.
The FAA said it was working to restore a system that alerts pilots to
hazards and changes to airport facilities and procedures that had
stopped processing updated information.
It also said it had ordered airlines to pause all domestic departures
until 9 a.m. ET (1400 GMT) to allow the agency to validate the integrity
of flight and safety information.
More than 760 flights were delayed within, into or out of the United
States as of Wednesday 6:30 am ET (1130 GMT), flight tracking website
FlightAware showed, without citing reasons. Another 91 flights within,
into or out of the country were also canceled.

Shares of U.S. carriers fell during premarket trading on Wednesday.
Southwest Airlines was down 2.4%, while Delta Air Lines Inc, United
Airlines and American Airlines were down about 1%.
"The FAA is still working to fully restore the Notice to Air Missions (NOTAM)
system following an outage. While some functions are beginning to come
back on line, National Airspace System operations remain limited," it
said on Twitter.
A NOTAM is a notice containing information essential to personnel
concerned with flight operations, but not known far enough in advance to
be publicized by other means.
Information can go up to 200 pages for long-haul international flights
and may include items such as runway closures, bird hazard warnings and
construction obstacles.

United Airlines said it had temporarily delayed all domestic flights
and would issue an update when it learned more from the FAA.
Germany's Lufthansa and Air France both said they were continuing to
operate flights to and from the United States, while the French
airline said it was monitoring the situation.
"Arriving and departing passengers can expect delays this morning
and throughout the day," Austin-Bergstrom International Airport said
on Twitter, adding that there were ground stops across the country.
A ground stop is an air traffic control measure that slows or halts
aircraft at a given airport.
In an earlier advisory on its website, the FAA said its NOTAM system
had "failed", although NOTAMs issued before the outage were still
viewable.
A total of 21,464 flights are scheduled to depart airports in the
United States on Wednesday with a carrying capacity of nearly 2.9
million passengers, data from Cirium shows.
American Airlines has the most departures from U.S. airports with
4,819 flights scheduled, followed by Delta Air Lines and Southwest
Airlines, Cirium data showed.
