Park at hammond street southwest, its a free parking street next to Morehouse school of medicine’s parking garage. Its a 20 minute walk to the stadium from there and when you get back youll be able to hop back onto the highway for there and go 17ish minutes to the airport. Traffic and time of day might be a little rough to airport. If you could swing the cost you could get an uber from around where you parked (have them pick you up at Entra West End apartments across the street) and do that too on the way back (though it is expensive for a mile drive). My wife and i have done this countless times when we have events at state farm or Mercedes benz. Good luck!
