Keep in mind you've landed in Phx...sunshine for over 300 days each year and at many times during the year the BEST weather you'll find in the U.S.
I've traveled in and out of Phx for the last 20 years and they continue to make improvements to upgrade your experience. I fly mainly out of Terminal 4 and there are many options to shop, dine or enjoy beverages while you wait for your flight.
Sky Tram addition for parking is super convenient.
