Welcome to Flyertalk foodoo
Welcome to Flyertalk foodoo, welcome in particular to the BA Board, and I very much hope your post today will be the first of many. Please make yourself at home, welcome on board.
I think you have had your answer. My understanding is that you won't be charged a telephone service fee if you add on the return later. I believe it's OK to book the initial service either online or by calling, as you indicate you definitely need to call for the return service.
