Hartsfield–Jackson Atlanta International Airport (ATL)
Shaky Knees is located just a couple of miles from Downtown, and thankfully getting from the airport to Downtown is quite easy. The airport is 10 miles south of the city, but you can use the MARTA train to get to downtown. The Gold Line train picks up at the airport, only costs $2.50, and is about a 25 minute ride into Downtown Atlanta. You can go with an Uber (about $15-20), but we highly suggest avoiding Atlanta traffic and just go with the train.
$2.50 each way on the Gold Line
