Easy desert stopover
Well organized, plenty of natural light, and the train makes moving between terminals painless.
It can get sweltering near some of the windows in the height of summer.
Phoenix turned out to be one of the smoother airports we've flown through as a family. The layout is clear, security moved along, and the connector train kept the kids entertained while getting us around. The desert sun does heat up the glassy areas, so we sought out shadier seats.
