A few years ago we could find cheap flights but I'm not seeing much now under $650ish without taking 1am flights.

Starting to look at BWI or EWR but also wondered if anyone has found better pricing by going to MIA or SJU then taking a smaller Caribbean airline that doesn't show up on code sharing sites.

Any suggestions for places to look that I might be missing? Traveling with 4 adults with potential for two more in mid October.

Thanks for any help.
