Narrative:

Air carrier X denver to philadelphia, jun/tue/99. En route we encountered continuous light turbulence at FL330, so we descended to FL290 for the remainder of flight. We were required to deviate around a fairly large group of thunderstorms in the midwest. Also, when we arrived in philadelphia we received many delaying vectors prior to our approach clearance. This situation arises periodically when many factors change during a flight. The deviation for WX over the midwest and the unusually rough ride were unexpected.

Original NASA ASRS Text

Title: B737 CREW ENCOUNTERED TSTMS, TURB, AND DELAY VECTORS, WHICH CAUSED THEM TO USE RESERVE FUEL.

Narrative: ACR X DENVER TO PHILADELPHIA, JUN/TUE/99. ENRTE WE ENCOUNTERED CONTINUOUS LIGHT TURB AT FL330, SO WE DSNDED TO FL290 FOR THE REMAINDER OF FLT. WE WERE REQUIRED TO DEVIATE AROUND A FAIRLY LARGE GROUP OF TSTMS IN THE MIDWEST. ALSO, WHEN WE ARRIVED IN PHILADELPHIA WE RECEIVED MANY DELAYING VECTORS PRIOR TO OUR APCH CLRNC. THIS SIT ARISES PERIODICALLY WHEN MANY FACTORS CHANGE DURING A FLT. THE DEV FOR WX OVER THE MIDWEST AND THE UNUSUALLY ROUGH RIDE WERE UNEXPECTED.
