My question is around adding Europe to an award trip to Hawaii (nothing is booked yet). My home airport is PHL. Looking to fly AA on the Hawaiian potion and BA on London portion. I get the concept, but can't get my head around dates lining up: Flight one: LHR - PHL (stop) PHL - DFW - HNL. Let's say I want to do LHR-PHL on April 1 and the Hawaii flight on October 1. Flight two: HNL - DFW - PHL (stop) PHL - LHR. I can book the Hawaii portion on October 10, no problem. But, I will have to book the LHR portion after that....say October 12, right? Even though it is clearly playing the system, would AA allow me to reschedule the PHL-LHR segment to April 7 prior to the Hawaiian portion? Hopefully the answer is yes - that would be pretty cool. If no, are there any other options rather than buying/booking another one way? Thanks all!
