SpaceAce, the answer to your question is no. The only time a fare would go down within a 2-4 day period prior to your flight is if a weekend esaver is offered. They come out on Tuesdays and Wednesdays and are valid for departure Friday or Saturday (depends on the airline) with a return the immediately following Monday or Tuesday. The only other time would be right before a holiday, but more than 1 day out.
