Correct, but upon checking the SAN-JFK flights, you will see that DL is using the 75Es [ex-TWA birds] with business elite seats. But, since SAN-JFK is not covered in the transcontinental BusinessElite program, passengers on this flight will experience the standard DL domestic F service. That sucks, because ALL of the SAN-JFK flights are using the 75Es, but that is probably seasonal and in the summer those birds will probably return to their usual TATL missions.

Looking forward to try UA p.s. one day... Also I am waitlisted for an upgrade on a DL LAX-JFK flight, but highly doubt I will get it...
