Even though the FCFEL is never refundable, the FCFL isn't always refundable. You have to inquire with Delta about each particular ticket, since the link to tell you the fare rules is always broken (at least the last several times I've clicked on it over the last couple years).
You don't generate sky miles credit on FCFEL but do on FCFL.
