I always connect here because I fly US Airways from Las Vegas. But everytime I have a stop over here, other than a major back track to the Bay Area, I don't really mind coming here because it's a well maintained airport. It might look old but it is always clean.
I'm only here about 1 or 2 hours at a time but I can't help but notice all these restaurants in here, if you're hungry and don't mind 'airport prices', never fear selection is here.
Also be prepared to walk close to a mile to your connecting flight. There's LONG hallways here. Don't worry, they have standing walking escalators.
