I am flying with AA on March 22 to Guatemala. My first leg is out of O'hare, I then land in Miami with an hour and a half layover and then take off to Guatemala. My initial flight out of ORD wouldn't be out of the international airport, correct? And I shouldn't have to reclaim my bags in Miami, right? Is Miami similar to ORD, where my flight to Guatemala will be out of a non connecting airport?
