The training department at US does a really good job, and the TEM model, use, and instruction are VERY integrated, as the previous poster said. It works pretty darn well. That said, US has its 1%-ers, same as any other airline, that do stupid stuff like has been mentioned by posters in this thread, US, AA, and otherwise.
Don't paint the whole airline on the actions of a few tools. On the whole, I find our pilots at US to be a safe, reasonably efficient, and CRM-conscious group.
