Only because Delta generally using lower-number routes for international flights. Delta (and other airlines) market some flights such as DL001 (MCO-JFK-LHR) as "direct". This is different from non-stop. If I search for flights from MCO-LHR, the direct flights will be higher in the search results, even though I have to stop in JKF (and change planes!). The other wrinkle with direct flights with a stop is that you only get the miles of the direct great circle routing! It's only about 60 miles different in this case, but there are worse examples.
That being said, if you book DL001 in the premium cabin from MCO-JFK, you'll be booked into a Biz fare bucket. The service (hard and soft products) will be domestic first, however.
