Seven concourses and an underground train between them sound worse than they are, but budget the extra time anyway, especially if F is on your itinerary. What you get for the hassle is $89 fares in February, a $15 meal on Auburn Avenue, and instalment options through Affirm, Afterpay or Klarna at checkout. This is a city for people who want the Martin Luther King Jr. National Historic Site and the BeltLine, not a lounge chair, and Delta's dominance means there is almost always another flight if you miss yours.
