I don't understand why people keep posting about traveling during the holidays and being surprised it is so expensive. Thanksgiving is one of the busiest time of the year to travel!
OP, I would look at Google Flights. You can put in your destination, how many stops you want to make, and then look at all dates. For example, I just put in earlier dates in Nov and got American with a stop in Miami for $434 r/t out of DCA.
