The Phoenix Sky Harbor Airport is good for quick layovers, but not great if Phoenix is your final destination. If you have to get a rental car, you have to take the rental car shuttle a good 10-12 montues away to the rental car place. And when you return the car, same shuttle to the airport. I noticed these shuttle drivers do not help with luggage. That's rough.
Also, the bathrooms are always flithy. Nasty.
I think the food here is okay. The places are small and generally do not have much seating. You just eat out in the gates. The sit down places are all terrible, like Zinc. Cartel coffee in C and La Grande Orange in D are exceotions - but both are grab and go places. I just find this airport inconvenient and dirty.
