Turn into the airport via Tucson Boulevard. Follow the road until it splits and becomes one way. After this step, you'll only follow the one step specific to the lot you wish to park in.
Bear left at the first opportunity to park in the daily parking lot. To park in the hourly parking lot, bear left at the second opportunity, onto the Lower Roadway.
Take the first right onto Airport Drive, and then right again at your first opportunity to park in the Cell Phone Waiting Lot. This lot is available only if you'll be waiting in your vehicle to pick up a passenger.
Follow the Upper Roadway past the terminal, and turn right onto Airport Drive. Turn right again onto Los Reales Road -- your first available right turn -- and follow it until you reach the Garage Parking.
Follow the Upper Roadway all the way to its end. Turn right onto Corona Road. Take your first right for Economy Parking, and your second right for Economy Covered.
