Here's a list of the only airports in the US authorized to handle charter flights to HAV: ORD, ATL, BWI, DFW, MSY, PIT, TPA, MIA, FLL, SJU, and JFK.
As to who's chartering the flights, many "universities" and "companies" charter flights. I put these in quotes because in reality there is a wide array of people using these flights, such as tourists (which is technically illegal).http://online.wsj.com/article/SB1000142 ... 86950.html
The list is out of date. There is currently service by Continental from LAX. Other airports recently approved include IAH
, and EYW
. EYW is limited to aircraft with less than 10 seats.

(hopefully this will be updated with the 2012 schedules)
