Very efficient, clean and spacious airport. Sky Harbor has the space to accommodate modern travel needs as apposed to some older, smaller more land-locked airports. Getting in to the airport is rarely a hassle. Both short term and long term parking are well marked, easy to find and easy to then get into the airport. Curbside pick up (arrivals) does get a bit congested though. T4 has plenty of food and shopping options, many have a high-end feel.
