The AA website limits you to 6 city pairs, but that can be more than 6 sectors. For example, if you enter LHR - PHX it will offer you flights via JFK, ORD and other cities as well as direct flights and it will show you very clearly what the final fare is likely to be for each option.
I find the AA website to be a lot easier to use, and less prone to errors, than BA's.
