Compare the cost of buying just AAA-BBB and BBB-CCC to buying the three of them together. Which is more expensive? If AAA-BBB and BBB-CCC add up to less, purchased today, than you paid for the set of them before, then make the change, cancel the last leg, and get some travel credit he can use on a future trip.
