The bodies were spotted along with debris floating in the Java Sea off the Indonesian part of Borneo, in one of the search zones for the plane.
Indonesia's search and rescue agency confirmed the debris was from the plane.
Six bodies have been found and at least three recovered during the search for missing AirAsia Flight QZ8501.
The operation, led by Indonesia, includes assistance from Malaysia, Singapore and Australia, with other offers of help from South Korea, Thailand, China and France. The US destroyer USS Sampson is on its way to the zone.
Divers and ships with sonar equipment are also being sent to the site, where the water depth varies between 25 and 30 meters (about 80 to 100 feet).
Indonesia AirAsia's Flight QZ8501, an Airbus A320-200, lost contact with air traffic control early on Sunday during bad weather on a flight from the Indonesian city of Surabaya to Singapore.
