Second this one. Seems like a great opportunity to avoid a JFK to LGA ground transfer altogether. If OP is in paid D1 and doesn't have to worry about award space, the schedule change may also give OP the opportunity to move to an AZ codeshare as well, if OP would prefer AZ over DL or find another routing besides even ATL (via AMS, CDG, etc.).
OP what is your final destination?
