Two flight attendants were evaluated for nausea and dizziness after a flight took off from Sky Harbor Friday morning.
American Airlines flight 1100 was leaving Phoenix for Baltimore when passengers started to complain of a smell on the plane.
The plane was turned around after the workers started to have symptoms, and landed safely back at Sky Harbor around 9:45 a.m.
The Phoenix Fire Department originally reported at least eight people were suffering from nausea and dizziness, but only the two needed to be evaluated after landing.
Phoenix fire says the burned rubber odor went away after takeoff, but the flight returned back to Sky Harbor out of an abundance of caution.
