I have a layover in DC in a little over a week and I'm doing some research on it because I've never flown out of there before. That's the airport I'm dreading the most because my plane will land in DC at 7:50 and the scheduled departure for my other plane is 8:30. I'll be using American airlines my whole trip to make it easier. I've been doing some digging and from what I gather I'll have to go through security every single time I want to enter a different terminal? I've never heard of that before and it seems excessive considering I would have already gone through security at my initial airport. Am I reading this wrong? Or can you walk between terminals without having to go out of security? If I do have to go through security, I'm doomed with this short layover aren't I?
