The plane carrying Houston's body is the private jet of filmmaker Tyler Perry, who offered his private jet to Houston's family for the trip.
Earlier in the day, Beverly Hills Police told reporters Houston's body had been found underwater in a bathtub in the Beverly Hills hotel room in which she died, but they declined to speculate on the cause of her death at age 48.
Houston died in her room at the Beverly Hilton hotel in Beverly Hills Saturday, where she was scheduled to attend and perform at music executive Clive Davis' pre-Grammy party.
The singer, best known for her hit single "I Will Always Love You," the theme song of "The Bodyguard" film in which she starred, had a long history of addiction to alcohol, cocaine and marijuana and had been in rehab as recently as May 2011.
