The FAA has confirmed to News 8 there is a ground stop in effect where American Airlines flies until 4 p.m. Officials with American Airlines say they cannot access their reservations and booking tool.
Flights on regional affiliate American Eagle heading to Dallas, Chicago or New York's LaGuardia Airport have been stopped until 3:30 p.m. EDT.
"Our system being down also affects out aircraft since that is how we report weight and balance," read an American Airlines tweet. "Our apologies for the delay."
Some passengers are stuck on planes while others can't make reservations.
Passengers are using social media to flood the airline with complaints.
American Airlines spokesman Kent Powell said Tuesday that the airline is trying to resolve the issues as quickly as it can.
On Twitter, American is sending out apologies but not offering customers much information about when the problem will be fixed.
An FAA rule that went into effect in April of 20120 states that airlines that do not provide free food and drink on a plane that has been grounded for more than two hours or does not allow passengers to disembark after three hours face a fine of up to $27,500 a passenger.
In another incident Tuesday afternoon at Dallas/Fort Worth International Airport, a heavy police presence was at the scene where a suspicious device was spotted at D/FW's Founders Plaza. A man in a protection suit approached the device just after 2 p.m. and the plaza was given the all-clear and re-opened at about 2:22 p.m.
