Depends on the airport you are commuting out of in south florida. my recommendation is go to passrider.com and plug in your airports look at how many flights per day. Usually you can only commute on one end, most commuters like to get home same day after a trip. So look at how late flights run back to get you home. From my experience south florida to EWR is an easy commute, LGA doesn't have as many options, but its doable.
