Airlines price routes independently. Sometimes flying A → Chicago → B costs less than A → B direct. The difference is your savings — and Chicago is your free city.
United uses O'Hare as its primary hub — one of the busiest airports on earth, and the Blue Line runs 24 hours so the stopover works at any hour of arrival. The Chicago Architecture Foundation river cruise is the best one-hour architecture education available anywhere in the world. Pequod's moves caramelised-crust deep dish from 11am. Do not order Giordano's.
