Not sure what the current fare is and it depends on your dates, if you are looking for summer travel I think the average is probably $1300pp. As I said it depends on your dates, the weekdays tend to get you lower fares, check the web site and the airport codes for your cities are SBA to FLR. Best of luck to you.
