No problem. Also, FYI, you may get different fares and flights depending on whether you book A-B, B-C, C-A vs A-B, B-C, C-B, B-A (even if the dates are exactly the same), so it is worth trying both options. This is definitely true when trying to replicate these itineraries on united.com, where it never seems to show all the options available on a single search.
