Maybe I should've booked the whole thing as a KLM ticket?
Correct, by the entire ticket on KLM. Delta recognizes and treats you better on KLM stock than KLM does on Delta stock. It is a nightmare and you can do a search on many KLM threads about getting econ comfort seats for elites, and having your seats moved.
