The problem every year (even without weather problems) is the fact that there is alot going on in Florida this weekend. The simple truth is that they overbook the chit out of the flights.....weather REALLY screws it up on top of that (if it turns).
That Daytona 500, the boat show and there is usually some huge ***-azzed art show going on as well. I made the huge mistake of flying stand-by on some Delta buddy passes back in 2000. Got booted off in Atlanta and ended up to not getting a seat on the next 12 flights. We ended up renting a car and driving from Atlanta to Miami. We had to do it.....our luggage made it to Miami on the original flight!!
