Sporadic sub-$100 availability on NYC-ZMA r/t throughout March and April.
$54-64 r/t on Spirit (LGA-MIA)
$92+ r/t on JetBlue (JFK/LGA-FLL) (note: Blue Basic fares)
I have not tried pricing out individual ticket combinations on multiple airlines. In the past I have seen $97 r/t Main Cabin (non-basic) fares from JFK/LGA to MIA and back on AA.
