Am I missing something or ExpertFlyer does not cover all possible AA award routes from Europe to the US?

To avoid BA, I have to search for Iberia availability on Qantas.com and for Air Berlin availability on BA.com

When searching for example LIS-LAX, it only shows LIS-PHL-LAX or LIS-London-LAX. It doesn't show LIS-MAD-LAX (Iberia), or LIS-DSF/TXL-LAX (Air Berlin).

That is one question.

The other question is when searching for awards with AA selected it shows me UA flights for some legs? I can't fly UA with AA miles. For example, http://i.imgur.com/48VMo8p.png
