RULE 5: INTER-AIRPORT TRANSPORTATION When a metropolitan area is served by more than one airport and the passenger requires connecting service with arrival at one airport and departure from another airport, transportation between those airports must be arranged by and at the expense of the passenger. Baggage must be claimed and rechecked by the passenger.
Incorrect. Where did you get your rule 5 from? You left out key bits to this discussion:

"RULE 5: INTER-AIRPORT TRANSPORTATION
Except as otherwise specified below, Delta does not operate or provide ground transfer service between airports or between airports and city centers. When a metropolitan area is served by more than one airport and the passenger requires connecting service with arrival at one airport and departure from another airport, transportation between those airports must be arranged by and at the expense of the passenger. Any such service is performed by independent operators who are not and shall not be deemed to be agents or servants of Delta. Although Delta may assist you in making arrangements for such ground transfer service, you agree that Delta is not liable for any act or omission of any such independent operator. If we issue you a voucher to cover the cost of services provided by any such independent contractor and you decide not to use the services, the voucher for such services will have not refund value.
Except for passengers traveling on award tickets or free tickets, Delta will provide ground transfer services at no additional charge to Delta or Delta Connection passengers making connections between LaGuardia Airport (LGA) or Newark International Airport (EWR) and John F. Kennedy International Airport (JFK) to or from Delta transatlantic flights, if the passenger's connecting flight is scheduled to depart the same calendar day of the scheduled arrival of the passenger's flight at LGA/EWR/JFK airports. Both the arriving and departing flights to/from JFK/LGA/EWR must be on the same ticket.
When transferring between airports, baggage must be claimed and rechecked by the passenger."
