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.
The major cities to fly to are Las Vegas, Nevada, or Phoenix, Arizona. From each there are commuter flights to Flagstaff, Arizona, or bus tours to the Grand Canyon available. The nearest town of any consequence is Williams, Arizona where you can catch a ride on the Grand Canyon Railway to the park.
