For those that have departed the U.S. through Houston international, I have a silly question for you. First time flying international as a civilian so I am not sure what will happen with my bags once I reach Houston or who would be responsible for them. Once I depart my plane in Houston do I then need to go to the luggage collection conveyor thingamajigger and get my bag and then head off to the international terminal and once at the international terminal once again check my luggage? Or once I leave Tucson will my lugage be checked all the way through to Belize city?
