MIA, TPA, MCO, JAX, JFK, LGA, EWR, PHL, DFW, IAH, LAX, SFO, ORD, DAY, MEM, CVG, and MSY are correct.
FLL, PBI, BOS, BDL, PIT, CMH, IND, STL, MCI, SAN, and LAS are incorrect.
If you wanted to fly from ATL to LAS, you could take a DC-8-61 nonstop, or a 747-132 via DFW.
DL's only ATL-SAN nonstop used a very rare 727-95.

10. Delta’s ex-Northeast fleet of 727-95s was down to five aircraft by 1976, and all would be gone within a year. There are 24 flight numbers (not flight segments) flown with 727-95s. Delta had scattered the 727-95s throughout their system, mixed in with their much larger fleet of 727-200s, instead of confining them to ex-Northeast routes. No 727-95s served BOS or YUL, and LGA was served by just two 727-95s per day. One flew on an ex-Northeast route nonstop to its destination, and the other flew on an ex-DL route, with one enroute stop to its destination. Name the routes.
The ex-DL route is LGA-CLT-ATL. The ex-NE route is not LGA-MIA.

12. Another bizarre flight I found in the timetable was a 727-200 from Baltimore to DCA, on a routing of xxx-xxx-BAL-DCA. Where did this flight originate, and what was its one enroute stop before Baltimore? Hint: the flight did NOT serve any legacy Northeast cities, and it did not originate in or stop at ATL
