I've only transferred through the PHO a couple times (so I can't comment on the security), but I think it's just A-OK. \n\nHighlights\n+Gates have plush seats.\n+Not overwhelmingly large, so going from terminal to another isn't too bad. (Vy is absolutely right.)\n+Free WiFi.\n+The mountains surrounding the airport are gorgeous. \n\nDrawbacks:\n-I understand that airports have their fair share of chains, but this one seems to have slightly more.\n-Bathrooms are kind of bleh.\n-Not enough seats at gates. (Saw too many people sitting on the ground waiting for their flights.)\n-Too many people riding on the golf carts and drivers not telling people to get out of the way. (Like me.)\n\nThis airport is the definition of mediocrity.
