The following is posted for a CA-FL route. I realize the max usually happens during holidays. However, I generally see fares around $600. If your chart could give a graph of when the min and median cost occur (and/or when one needs to buy them), I would find it truly helpful. Sometimes I can plan well in advance of when to visit someone but I don’t know how to ever see these low prices.
