ok I'm back again with an update. So I changed to the later flight to have a longer layover and twice they have changed this flight as well. I'm so screwed. I went from a 37 min layover and changed my plane ticket to the later flight and now Delta knocked the layover from 1 1/2 hrs to 1 hour EXACTLY. I'm coming in from MEM which usually is on time and I'm on a Canadian Airjet like 7th-8th row so I'm pretty close to the front. We will NOT be bringing anymore than small backpack cause you know it can take a few minutes to get carry on's outta the plane into the gate area.

Oh and this is the last flight Delta has going to Mobay that day. There are only two on THanksgiving. My luck go figure.

As for arriving in ATL from another domestic flight after reading all the comments which I greatly appreciate, I'm confused.
Can I take the tram from a domestic terminal to the new Internation terminal or do I have to wait for bus? If its a bus where do I catch it? So confusing.
Someone told me it runs only every 15 mins, but I think that's bogus...can someone verify its faster than that?

We are flying Business Elite in First Class on the trips from ATL to Mobay and Delta offered to provide us with an assist in one of those carts, but I am starting to feel very guilty about using that when someone who might not truly be able to run (unlike the 2 of us) won't have that option. On the other hand I haven't been in ATL in years and really worried I will take a wrong turn.

Honestly if I could just run through the airport I could probably find it easier than waiting on a bus, tram, etc.

I remember the days when you could have someone call the departing gate and let them know you were on your way. Guess those days are long gone.

Any suggestions i'm open. 1 hr and that's hoping there are no delays.
