Hi, I had booked a flight, LAX-LHR-Croatia, return Croatia - LHR-LAX. I had 2 separate itineraries one for the LAX-LHR I purchased and the croatia flights were purchased on miles, all on AA/BA. Today I upgraded my LAX-LHR using evip's, I was able to avoid the luxury departure tax by showing that I was in LHR < 24 hours each way (Thank you everyone on this forum for getting me that far). My question is when I originally purchased the LAX-LHR in Y, they charged me APD, should the APD be refundable in this instance? EXP didn't seem to think so, that I only avoid the extra luxury tax with my stay in London being less than 24 hours. Hope you all can help. Thanks,
