Actually, the (outrageous) $1,595 pp one way is the fee that I initially paid for the Miami route. When reconsidering whether to reroute thru Charlotte, I checked the AA website for fares. The Charlotte route was listed as $890 pp. I asked if I would be refunded the difference for this less-desirable route, but was told NO. Anyway, we decided to go thru Charlotte to avoid being stuck in Miami overnight in case our SXM flight was delayed due to weather.
