I did the same thing last night, Todd: changed from a three-leg return to the two legs thru MIA with no overnight. I was surprised that the price showing on my confirming email was less than what showed on the web site and is less than what I originally paid ($5xx vs $6xx). I am not going to bother trying for a refund. This will be the first time in a long time that I get home on the same day I leave, assuming the flights stay as they are now.
