I don't spend a lot of time here on each trip, because I'm the kind of guy who arrives via Uber at the last minute with carryons only, zips through TSA as quickly as possible, and usually gets to the gate within just a few minutes of boarding.
That said, I have accumulated a lot of time here over the last 14 years, and I find T4 to be one of the better major airport terminals I've dealt with. Long and short term parking are conveniently located and easy to negotiate - especially East Economy garages to T4 by Skytrain. There's ample dining pre and post TSA. And speaking of TSA, I'm not pre-check but I am seasoned "elite" and I usually end up spending 15 minutes tops in the A gates security line. Many trips are 5 minutes or less.
My only complaint is that there should be more "afterhours" dining available.
Otherwise, keep up the good work PHX (and PHX TSA).
