Note however, that even if you fly into the Grand Canyon airport, it will cost you quite a bit and there are many overlooks and other parts of the canyon that you need a car to reach. I would recommend just flying into Phoenix and then getting a cheap rental car.
1 The Grand Canyon Shuttle is no longer in business.  The (928-638-2820) runs between the north and south rims of the park once each day, in each direction, between May 15th and October 15, with a limited schedule between October 16 and October 31.The travel time is about 4 1/2 hours each way. Reservations required.
