Hi everyone. I will be flying out of ATL in Sept. for the first time. Domestic flight. I have never flown out of ATL before. Have flown out of JAX for the last 32 years. Where is the best place to park? From the time i park how much time should i alot to get through security and to my gate? I will be flying on Southwest. Any other info about ATL would be helpful. Departing flight will be on a Saturday around 8am. How busy will ATL be at that time?

Again thanks for any information.
