I have a question for those who are familiar with ATL.

My aunt will arrive in concourse F off an international flight and has a 2h30 connection time to a domestic flight that seems to usually leave from concourse T. She is becoming less confident with her walking and is a little less steady on her feet than she used to be, but is far from needing a wheelchair.

While I am less familiar with ATL, I understand that she'll clear immigration and customs at F and then need to proceed to T with her wheelie hand-lugagge.

She does't feel confident taking the train as it does't seem to have seats and the acceleration at stops may cause her to lose her balance.

Does the walking tunnel between concourses have moving walkways throughout? (I know there will be gaps between them but do they stretch between all concourses?) She would be ok with these. If so, does anyone know roughly the travel time from F to T using them?

Also are golf carts available for travel through the tunnel? How would she go about requesting one?

Thanks in advance.
