Fly nonstop from Miami to New York-LGA or JFK for $101 roundtrip this winter/spring. This fare also works in reverse for those NYC based flyers looking to head south for the winter.
Flights are available on both American and Delta at this price point, but dates are a bit harder to pin down. Availability is fairly sparse in certain months, but it is out there! Your best bet is to try and book two separate one-way tickets at $51 a piece and stitch together a custom itinerary of your own.
As an example, searching on AA.com, I found weekend travel departing MIA on Friday, January 25 and returning from LGA on Monday, January 28, 2019. Dates in January and February seem to have more seats widely available.
There are a lot of deals out of Southern Florida at the moment. So make sure to have a look at our Miami (MIA) and Ft. Lauderdale (FLL) flight deal pages for a full list of what's on sale.
