Southwest Airlines says a plane that took off out of Phoenix Sky Harbor International Airport was forced to make an emergency landing in Amarillo, Texas.
A plane heading to Atlanta from Phoenix on Saturday developed an issue with its pressurization, an airline spokesperson said.
Following emergency procedures, the pilots and flight crew decided to land at the nearest airport after reaching a safe altitude.
Emergency personnel was on-hand in Texas to help any passengers but no injuries were reported.
The aircraft was taken out of service and is being inspected and repaired, airline officials said.
The passengers were transferred to a different plane and Southwest is apologizing to anyone that this incident has inconvenienced.
