So if the airlines are asked to divide up 110 flights a week, that's probably no more than 30/week for American as an incumbent. I think you let the ULCC take the smaller airports, and focus on HAV and developing the government and NGO travel, as well as the connecting business travel from other countries into MIA:

3x MIA-HAV Mon-Thu (12)
4x MIA-HAV Fri-Sun (12)
1x TPA-HAV Fri-Sat-Sun (3)
1x JFK-HAV Fri-Sat-Sun (3)
