Hey Twister I was hoping you might chime in. And thanks to all the others for their comments and suggestions as well.

I'm on the fence with this one. Reality is we will have about 40 mins to jump off the plane and get on the plane to Mobay in the ATL airport.
There is another flight that leaves outta MEM at 8:47am arrives in Mobay at 3:05pm. It has a 1hr 1/2 layover.

The safe girl in me says switch flights and go with the longer layover at ATL. The risky girl in me says "stick with the short layover and run like hell thru the airport, because you are only in JA for 5 days including this day of travel." Still either way I also have to consider its on Thanksgiving Day which could mean a very crowded airport....but also more delays in my favor..

Delta told me we could switch flights at anytime for free. And if we want to take the chance they will try to get us on the next flight out....provided there is enough seats available for us.
Right now the later flight is wide open, but Delta suggested I keep checking it as Thanksgiving is a long ways away from July.
