A US Airways Airbus A319-100, registration N808AW performing flight US-496 from Phoenix,AZ to Denver,CO (USA) with 93 passengers and 5 crew, was on approach to Denver descending from FL390 through FL330 when the aircraft encountered severe turbulence. The crew subsequently reported two flight attendants had been injured and declared medical emergency requesting paramedics at the gate. The aircraft continued for a safe landing on runway 35L about 17 minutes after the turbulence encounter and 10 minutes after requesting medical services and after several ATIS updates. The aircraft taxied to the gate, where medical services had not yet arrived about 15 minutes after the request. One flight attendant received serious injuries (fractures), one flight attendant and two passengers minor injuries, the aircraft sustained minor damage to the interior of the cabin (cracks in cabin ceiling).
