Destination guide
Chicago: Big-shoulders architecture and a lakefront for everyone
Chicago is America's most connected inland hub — O'Hare and Midway between them have nonstops from nearly every US city — so fares are consistently reasonable. The lakefront, the architecture and the food make it a strong long weekend.
Best time to visit: June–September is warm, with festivals almost every weekend (and the highest hotel rates). May and October are cool and cheaper; winter is cold but hotels are a bargain.
