The recent upgrade was great, but only about 2/3rds of the gates are new. And the old ones (due to be replaced) are small and very crowded. And hot in the summer and cold in the winter. Still a better choice than the mess at O'Hare. Half the cab fare and much more compact.
Great low-cost carriers, too.
Pros: Compact, Great Subway Access, Good Food Court
Cons: Tough Connection to O, White-Knuckle Landing, Limited Aircraft Choi
