That's my point - a RTW itinerary can have four tickets (each ticket having four flights, for a total of sixteen)
Another question related to RTWs after AA switches to revenue-based RDMs - when will the RDMs post to your account: after the first flight (doubtful), after each flight (how will they allocate the cost), or after the last flight which could be 12 months later?
Good point. We of course don't know how the revenue from a RTW is split between the carriers, and whether subsequent routing changes during the validity of the ticket can affect the revenue earning by carriers for flights already flown. An extreme example might be if the pax decides to add one or more continents to a Oneworld Explorer - how might that affect the carrier revenue for already flown flights

I suspect AA has given this no thought at all.
I wonder how DL and UA handle this for ST *A RTW products
Can we assume that any RTW booked (or started?) before the switch will continue to earn RDMs under the old miles-based system?
I don't think we can make that assumption. But just how AA will handle it remains to be seen.
