Clean, efficient, and friendly. Pretty much what you hope for in an airport.
Good representation for Houston.
The security itself was a bit overwhelming (always is anywhere though!)
But went by super fast, just gotta keep up! Little tip, personal items (wallets phones, laptops, shoes, etc) go in the buckets, bags and everything stay freely on the scanner.
Definitely try to be at the airport 1 hour before the flight boards so you can cover yourself through parking, security and grabbing a bite to eat, etc.
Check out the model of the ISS, super cool little info charts too.
I like the airport and this one is definitely a nice one to make travels happen.
