The best part of these cheap JetBlue fares is that there aren't many restrictions on dates. The lowest prices are basically universal, with the exception of holidays. Though if you're hoping to get away this weekend, you'll need to wait. Service from New York City doesn't begin until Nov. 28, while service from Fort Lauderdale begins Nov. 30.
A roundtrip ticket from Fort Lauderdale is currently running a reasonable $135, while flights from New York City are going for $205 (and may be climbing, since earlier on Thursday they were seen as low as $198).
