Daniella Muffler is a character in Cars 2.
"Daniella used to work as a waitress at the Flaps Down Fly & Drive-in near her small town's airport, and for hours she'd watch the planes land and take off. Fascinated by travel, Daniella got to know the local planes during their layovers. She was always courteous and brought them refreshments. One day, something dawned on Daniella— she could do her job up in the air ! The next day she signed up to be a Turboloft flight attendant."
