The passenger jets landed safely at Dallas Fort Worth International Airport within two minutes of each other, CNN reported.
Flight 1359 made an emergency landing at 12:21 a.M. after the pilot was alerted to a mechanical issue, airline spokeswoman Laura Masvidal said.
The McDonnell Douglas MD-80 plane had left for Fresno, California, with 140 passengers and five crew members an hour earlier.
Masvidal did not say what the mechanical issue was, the report said.
The second flight, AAL 997, was over the Gulf of Mexico on its way to Buenos Aires, Argentina, when a problem with pressurisation turned up.
Both planes landed safely, and the flights were rescheduled for later times, the report said.
