In about two months I will be traveling to San Jose, Costa Rica aboard American Airlines. I will go from DCA (my home) to MIA on a 757, and from MIA to SJO on an Airbus 300. Back is on an A300 and MD80. I've never been on an A300, nor have I been to MIA. Could anyone describe any experiences with American Airlines to Latin America. Also, how are american's A300, and whats SJO like?
