Searching JetBlue, I found seats departing Miami MIA on Wednesday, July 3, and returning from Grand Cayman GCM on Sunday, July 7, 2019.
This fare includes a carry-on bag and a small personal item.
Seat selection is available in advance with the purchase of this fare.
Returns are available on Saturday, July 6, for the same price. If you depart on the Fourth, this fare can be purchased for $314 roundtrip.
For other fantastic fares departing South Florida see our Miami (MIA) and Ft. Lauderdale (FLL) listings for a complete list of current deals. And for more travel deals over Independence Day, have a look at our dedicated page for Fourth of July Getaways.
