Shazzan

From: Wikipedia.org
Shazzan was a Saturday morning cartoon produced by Hanna-Barbera Productions in 1967 for CBS. The series followed the adventures of two teenage siblings (Chuck and his sister Nancy) traveling around a mystical Arabian world, mounted on Kaboobie the flying camel. During their journey they face several dangers, but they're always helped by Shazzan, a genie with magical powers out of this world.

The intro to the cartoons and the first episode give this plot description:

"Inside a cave off the coast of Maine, Chuck and Nancy find a mysterious chest containing the halves of a strange ring. When joined, the ring formed the word "Shazzan!" And with this magical command, they are transported back to the fabled land of the Arabian Nights. Here they meet their genie, Shazzan. Shazzan presents them with Kaboobie, a magical flying camel. Shazzan will serve them whenever they call, but he cannot return them home until they deliver the ring to its rightful owner. And thus begins their incredible journey."
