First leg:

IAD-LHR arriving 05:55

Booked using Avios (20k + $256; Not a great redemption, I know)

Second leg:
EY 12
LHR-AUH departing 09:15 of same day

Booked using AA awards

Process took 2 calls and around 2 hours. I booked the LHR-AUH months ago when I saw two open seats, only booked BA yesterday. First agent says that the incoming flight has to be mentioned before booking the second leg and told me to go online to refunds or reservations. (BS). Called up the second agent, told her the entire process of referring to the incoming flight's ticket number and asking her to contact the rates or reservation desk. She went away for about 45 minutes and came back to refund $214.40 a piece for the UK APD.

So, even for those of us that don't have access to EXP desk, a simple call to AA award reservation should do the trick.
