Just call and tell them you want Y for your domestic legs, and I for the TATL flight, and it should be cheaper than 2 separate tix.
YMMV.
And.....you should be in F for the domestic portions for that extra $10 (taxes) or so that you paid. Check and make sure that the agent didn't book you in Y because you asked for it

Your fare that you were quoted was a single JAX-LHR (not as two separate fares for domestic and international portions) fare for a Business Elite trip that includes F on domestic portions. Your situation and fare is significantly different than the OP fare. I believe that this fare is only good for MCO/JAX/TPA-LHR through BOS and is available for ticketing by the end of 12/31 unless DL extends it.
