In term of what you are looking for I Phoenix Sky Harbour is probably the best spot for you to photography. There are 3 terminals all with-in shuttle bus reaches and each has its own parking garage which all spotters used for spotting. There are hotels nearby on Broadway or Univeristy Dr. that provides shuttle free of charge to and from the Phoenix Sky Harbour. The only international you'll get here is BA
and the rest is domestic with heavy traffic all day long. Winter time between now and the end of February to the best time to spot. You'll have good lighting all day with great sun rise and sun set. PHX
airport itself is very friendly and police friendly also. Yes, they will do round from time to time just checkin-up, take info, photo-id and if not sometime they can chat up a conversation for hours. Most of the time you won't even be bothered at all. Here are some photos from the great local spotters.
Night photography is also magnificient here so you might want to give that a shot also.
Well you probably get the point, but feel free to e-mail any of these guys to know more about spotting at PHX
