The second bank of Caribbean flights starts leaving around 4PM.
It connects to the second bank. Yes, the layovers aren't all very short, but that's how it goes. AA will still capture the traffic, just like they do from Louisville.
Charleston also presents a strong local market (around 140 people per day with an average round-trip fare of $430), like Savannah, so its also important to have the flight well-timed for traffic terminating in CHS.
