A Southwest Airlines flight from Oakland, Calif., to Denver returned shortly after takeoff when a wing slat warning light made the pilot decide it was safer to turn around.
The plane was a Boeing 737-700 series, a different model than the jetliner that had a fuselage tear over Arizona.
Oakland airport spokeswoman Joanne Holloway said the Tuesday flight landed without incident about 7:30 a.m., and the 103 passengers were put on another flight about two hours later.
Southwest spokesman Chris Mainz says the wing slat, which helps slow and maneuver the plane during takeoffs and landings, is out of the pilot's field of view.
Holloway says the airport did not classify the event as an emergency landing but instead as a lesser yellow warning.
