But D1 aircraft should get D1 fares on JFK-SAN, not FC fares.

Update -- It looks like this is intentional and JFK-SAN is being dropped from D1 routes. There were new fare filings on 8/19 and JFK-SAN route was dropped from FC fare rules Flight Application section at that point. Here is part of modified Flight Application section ("757 200 WINGLETS" is fare rules speak for the 75S model -- not all 757-200s with winglets). Domestic D1 fare rules were similarly modified and JFK-SAN was removed from those as well. Award fare rules still have previous Flight Application sections which is causing some confusion on award searches.

FC fare rules before 8/19


FC fare rules effective 8/19


Here is current full Flight Application section for domestic FC fares. There are similar ones for domestic D1 fares, but the requirements are reversed and these flights are required instead of excluded.
