Thanks for the many useful tips. I do have another quick question: My itinerary is Rome-London-Dallas-Garden City Kansas. Once my bag is checked in at Rome, will I have to reclaim it at the other stops to pass through customs or will it magically go to my stop in Dallas in order to clear USA Customs? If I do decide to go into Rome, will I have to reclaim my bag and then recheck my bag again? Thanks for your continued assistance and patience!
