Chicago (ORD) to Johannesburg (JNB) - Fri, Dec 27
American Airlines Inc. Chicago (ORD) to London (LHR) - Fri, Dec 27
American Airlines Inc. 90 Dep: 8:45AM Arr: 10:40PM 7h 55m Boeing 767 Economy (M)
Layover in LHR 19h 20m
Watch that layover in LHR. There is a better option that leaves ORD at 6:00pm. make sure you get the right option when you book.
