Going Between ATL Terminals
 

I think I know the answer to this but.................

Is it possible to go between terminals at ATL without clearing security??

Reason why I'm asking is I have a layover with Delta bit no Skyclub access and will need to use the United Lounge.

You mean concourses?

Yes. Easily.

Oh! Yes, I suppose I do mean concourses............must've confused airports.
No security between concourses.

Thanks!

None at all. You can move between the concourses as you please.

Yep, T and A-F are all linked and don't involve more security. Just head to the middle of your concourse, descend the escalator, and take the people mover wherever you please. It's one of the few things I like about ATL - the ability to go wherever I want for food when I'm on a layover :P

You can also opt to walk rather than take the people mover / train between concourse. ATL has a great art collection in the corridors connecting concourses (visible once you pass the train stop)

Does this including arriving in a domestic concourse and departing from the international terminal?

Yes
