It says nothing about fare type. You should have access if you are in B/E on LAX-JFK.

As a data point, I have gotten SC access as an FO upgraded to X class on an LAX-GUA flight because it was international. So it shouldn't matter how you get into the forward cabin. If anything, AA allows Flagship Lounge access at LAX/JFK if you are in Z class (award ticket), so it shouldn't be different for DL since the SC access is to compete with UA/AA.
