We flew via Atlanta to/from Jacksonville in August. Our original Delta flight back from JAX to ATL gave us 65 minutes connection - tight, but apparently doable. However, when Delta changed the flight time to operate 20 minutes later, I suspected.
Virgin Atlantic confirmed that their recommended minimum "safeguarding" time for a connection would be 60 mins, so after a debate with Expedia who we had booked the flights with, we were rebooked onto the earlier 15:30 flight giving us 2h10 mins connection time. As we had lounge access at ATL, the extended layover wasn't a problem.
When we travelled, our flight arrived spot on time into Atlanta (at 5pm), and as noted above, we had to travel virtually the length of the airport from concourse B to F (the International Terminal). This took about 15 minutes, and as a bonus, there was no security clearance when we arrived.
As it happened, I kept an eye on our original flight which was due to arrive at 18:30, and had arrived at 18:10 so we would have been ok on this occasion. However, it would only take a 10-15 minute delay on departure to cause problems, so I would always err on the side of caution and take a longer connection time.
