Thanks for the suggestions. Just curious, is it really possible to pass through LHR that many times? Are stopovers permissible on all of those?</font>
You can stop in LHR (and most other places) as many times as you desire. The only restriction on stopovers is two in the continent of origin - Asia.
SJU-LIH is a valid single plane route for AA285 although it makes stops in MIA and LAX on the way.
christep: Nice routing!
