Delta Air Lines and Southwest Airlines, the two largest carriers at Hartsfield-Jackson International Airport, were not affected by a glitch disrupting some other airlines' passengers Tuesday morning.

Delta and Southwest combined make up about 90 percent of the traffic at the Atlanta airport.

The problems reported on airlines including American, JetBlue and Alaska came after a system issue on airline booking system provider Sabre.

Delta and Southwest use other booking systems.
