It's hard to write a fair review about Phoenix-Mesa airport because it's basically an Allegiant Airlines airport, and everything involved with that airline is sketchy.
TSA is pretty typical; take it for what you will.
Most employees are nice, or at least civil, but everyone who works here just looks miserable 90% of the time.
The grill has some decent food (sole reason for 2nd star), and I've seen worse prices in airports, but again, if you find yourself here, you're probably flying Allegiant and you've seen better days.
Short term parking will rip you off too, but that's because they know you'll pay anything to get out of there!
