Craig from craigslist and craigblog offers a good travel tip if you happen to get bumped from your flight:

"Well, let's say United has more problems, and they cancel your flight. Normally, they'll place you on the next one they have, not telling you another carrier has one that's leaving much earlier. While you wait in line, call the carrier, ask not only what's available from them, but also, what's available on other carriers. Life's much easier that way."

Thanks for the tip, Craig. Your Miami site is a great resource; we found our house and coffee table there.
