"More advanced" because it involved 2 reservations. That's also why the OP likely would not want to use the website to make a change...there is no way to know after changing the first reservation online whether or not there will still be seats available on the same flights to change the 2nd reservation. Easier, for the pax, to call in this situation, and ensure from the outset that everyone can be rebooked together.
