We are a family traveling to Italy this summer, this is our first overseas adventure and we are not sure what to expect in regards to the airport. We will be departing through our regional airport connecting to Dallas, from there Chicago, finally to Rome. Can you give me some idea what happens, what is the process/procedure here stateside in regards to an oversea flight? Check in procedures and such. Then we when we arrive in Rome what happens, what is the process/procedure? Much thanks!
