Hello - I'm interested in going on a family vacation 4-11 Mar to Panama, but we are open to other locations in Central America / South America. I would prefer to fly out of RDU, CLT, or ATL. I was looking to go AA through MIA, but the flights are filling up. I have 7 in my party. Any suggestions, on International flights from the east coast that are fairly open going to Central America / South America location that is good for a family location.
