Thread: Refund of UK APD (Air Passenger Duty) for in transit travel?

Not sure how the US res system is set up but we transit a lot thru LHR from BA to AA. Separate PNR reservations. When we check in with AA, we show our boarding passes from our connecting BA flight, get listed as a "thru" pax which bumps us up on the priority list above LHR originating pax thus avoiding the APD when they payroll deduct. Once the flight is completed, I don't think there is much that can be done.

What we haven't been able to figure out is when we arrive on AA and connect to BA. I guess because it involves a ZED, BA is unable (or unwilling?) to deduct the the APD. The last time we did this was when AA was still issuing paper ticket zeds so not sure if the new ezeds make any difference. At least the APD rates from LHR to mainland Europe are not as high as transatlantic. Still, it's a bit crazy that the LHR-___ flights are sometimes almost double ___-LHR flights.
