Hard to model in the sim, but Florida has shifting demand. During the summer/fall, Shuttle America will fly Embraers on the Florida routes, but during winter/spring, they'll use the Airbus. Delta uses Mad Dogs on a lot of their summer/fall routes to Florida, but 757s on their winter/spring Florida routes (they just switched back to the MDs this week).
So if it's June or July in the sim, then 200 is about right. If it's November/December, then 750 is about right.
