Honestly, pretty good.
American Airlines, connection only
Current Grade: A- (February 2018)
When I think of this airport, I think of competence. Too bad its offspring was less convincing.
There's good natural light, traffic flow through the American terminal was easy and straightforward, I had a better-than-average coffee, and there were decent options all around. Plus, extra credit for easy-to-read, well-placed, color-coded signage. Love a good wayfinding system.
This connection through Houston was part of my original airport review, so it's an early grade and might get an update next time I fly through Texas.
