Drive to the Airport

 

First – you are looking for exit 149 – Sky Harbor.  Take this exit to the right from interstate I-10.

 

Once you take the exit ramp, the next set of signs you will be looking for look like this – follow the signs for Terminal 4 (once you get past these signs though, get into the right lane because you will be making a right turn on the other side of the upcoming overpass). 

 

 

Then this is what you are looking for.  As soon as you get over the overpass after the last sign, you will see the cellphone lot on your right; get into your right lane and make a right at this intersection; go to the Stop sign and make another right turn, and there will be an entrance into this parking lot just about 100 feet after that second right turn.
