Yea, you definitely have access to the Flagship Lounge at LAX and Chelsea Lounge at JFK.
You
might have access to Flagship Dining at MIA too, if you want to try your luck and don't have anything to do in MIA

Accessing Flagship Dining the next day, one stop removed from your qualifying flight is YMMV territory, although most data points are positive.
(Similar data point: on 2 separate occasions I've flown the redeye LAX-BOS-JFK in F and J, in both cases it was no problem to access Chelsea and Greenwich at JFK)
