One of my several fave e-mail newsletters comes from Airfarewatchdog (we also post their deals daily on our website.) 
Just in are these eye-poppers. I'm cutting and pasting their whole list, but here are a few  highlights:
- Miami-Beijing, $861 roundtrip on Air Canada, good through mid-April
 - Miami-Munich, $408 roundtrip for winter travel on Lufthansa and United
 - Miami-Burlington, Vt., $179 roundtrip through early June on Northwest
 - Miami-Savannah, Ga., $149 roundtrip through April 1 on AirTran
 - Miami-Portland, Maine, $179 roundtrip through April 1 on AirTran
 - Fort Lauderdale-Denver, $198 roundtrip through June 25 on Southwest
 - Fort Lauderdale-Los Angeles, $204 roundtrip through May 21 on American
 - Fort Lauderdale-New York LaGuardia, $139 roundtrip through May 20 on U.S. Airways
 - Fort Lauderdale-San Jose, Costa Rica, $248 roundtrip this winter on American
 
You know the drill: Limited availability, some restrictions apply, etc.....which means you better buy fast.
