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.
Grand Canyon Airport is just seven miles from Grand Canyon's South Rim.
