The flight was restricted to FL250 due to an inoperative pressurization component. AIRMET 13C was in effect for a line of severe thunderstorms with tops above FL450 extending along and to the north of the flight route. The flight deviated to the south of the thunderstorms; however, moderate to severe turbulence was encountered 3 times in about 10 minutes with each encounter lasting about 5 to 10 seconds. The crew reported the encounter as clear air turbulence. The captain stated 'clear of clouds, no turbulence reported by ATC, nothing painted on our, or ATC radar on our flightpath, clearing nearest cell by about 35-40 miles.' One flight attendant, who was in the cockpit, reported sitting on the cockpit floor and holding on to arm rests during the turbulence. After departing the cockpit, she responded to a call from the seriously injured flight attendant.

Company personnel stated that the flight was restricted to FL250 due to an inoperative pressurization component. The crew reported that the passenger seat belt sign was "ON" and all passengers remained seated. En route at FL250 (54 miles on the San Antonio 262 degree radial) the flight deviated south of the thunderstorms; however, moderate to severe turbulence was encountered three times in a time span of about 10 minutes with each encounter lasting about 5 to 10 seconds. The captain reported the flight encountered clear air turbulence. He further stated that the flight path at night was "clear of the clouds, no turbulence reported by ATC, nothing painted on our, or ATC radar on our flightpath, clearing nearest cell by about 35-40 miles."

One flight attendant, who was in the cockpit, reported "puffy dark clouds, visible straight ahead through the cockpit windows when we entered them and the third event occurred." She further stated "I held on to both arm rest and sat on the floor until the turbulence ended." After departing the cockpit, she responded to a call from the injured flight attendant in the aft cabin.
