From your post it seems to be on DL, and so after getting through customs, you can just turn in your bags.
OK, so far, no definitive answer. Yes, it will all be on DL. After booking a LHR-JFK flight, I now find that I need to be in BOS. That will have to be a separate ticket on DL.
So, will I be able to get BOS luggage tags in Lindon when I initially check in for the JFK flight. And if NOT, after I claim my bags at JFK and clear Custome, will DL allow me to check them to BOS at the connection desk assuming I show ID and the onward ticket to BOS?
