I have a domestic connecting flight from Memphis to Dallas before my international flight. All the flights were purchased on one ticket. Once arriving in Dallas, will any of the steps or processes be different than if I were to just fly internationally straight from Dallas without the connecting flight? Will I need to check in again? Will I need to collect my luggage and check it again? When will they check my passport? Just wondering if anything will be different since I have a connecting flight first. I’m someone who needs clear instructions and likes to be prepared in every way possible. Even the tiny details and things like that. It makes me more comfortable, so I’m just checking. I’m not a very experienced flyer.
