I also noticed when I was checking for an AJ flight of Phila on the Ita site that under "flight details" it lists sun country. I have no idea what that means. I"m hoping to be on an Aj flight out of Phila within the next week or 2 and I'm going with the assumption that I'll be checking in at the Air Jamaica terminal.If not I"m sure someone will steer me in the right direction. Just wish the flights weren't so expensive!
