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.
If you are flying in to Denver International Airport or DIA you can opt to rent a car from one of the many car rental agencies and drive, take a shared shuttle, hire a private car, hire a limousine, or even cab it up to Keystone.
