Listing the routing as you have, has made some of us think you believe the plane that just flew PHX to LHR is going to turn at LHR back to PHX. Which, in the absence of any "tag" legs to/from PHX, means that in PHX the plane can only turn back to LHR and repeat. Thus my comment about "dedicated airframe".

I should have written it as LHR-PHX-LHR since the 772 will be used on another flight to either MIA or another base, since AA has a maintenance base in PHX, maybe they can do the A/B checks who knows
