Since the rule change just recently occurred I'm not sure anyone has a definitive answer for you. The thread I referenced does show some confusion on AA's part with even applying the rule change to xonex's that predate the rule change (when the rule change clearly should not apply). Call the rtw desk and ask and let us know what they say. While the LHR-LGW surface segment question doesn't usually affect me (I don't do that transfer anymore) JFK-LGA possibly would affect me in the future but not under my open AONE4 or ones I am currently planning.
