The itinerary you give nets 510 SCs.However if you had gone LAX-DFW-MIA-DFW-NYC-DFW-LAS-LAX you would have got 690 SCs.AA usually offer the LAX-DFW-MIA option as well as the direct and usually for the same fare.same NYC-LAS.
For mileage I use this site and your route should be up to get the mileage. Great Circle Mapper=
We are going Aug. so plenty of time to plan and book.
Not thought of going thru DFW again to get extra points, bit limited with time as have max of 17 days all up in US, so adding extra flight time might impede things. Then have to work out best flights as 2 class think I read AA have just Y and F on many flights, so auto upgrade brings more points.
There is 1 LAX-MIA flight a day which is 3 class so just be careful.
The thing about transitting at DFW is it is AAs main base so frequent flights.
So i just selected 16/8-AA280 leaves LAX at 0900 and arrives in MIA 1720.
Going via DFW then AA2428 connecting to AA484 you leave at 0845 and arrive 1955 with a 2 hour connect at DFW.So not a major loss of time and 90 extra SCs.
The cost was exactly the same whichever choice you make.
