Latest traveler survey I saw from a few months ago had ATL ranked as the best airport in the U.S. I live in the ATL area but haven’t flown in years so I can’t comment.
I remember the shuttles from the private parking lots were pretty efficient in getting me back and forth, and I didn’t have trouble inside the ATL airport getting to my gate.
I remember transferring through Baltimore, and my flights were always at the far end of the airport, seemed like endless walking. Flying out of Chicago there always seemed to be some type of delay.
ATL is also one of the busiest so that’s a feather in their cap
I am retired and don’t fly that often, but I think that for the number of people the Atlanta airport must deal with every day, it’s fine. I like it. I like things that work.
My son has to fly often for business throughout the country, and he thinks the Tulsa airport has been the best experience. It is quiet,clean, well organized, minimally stressful, and efficient - on a much smaller scale than is needed for Atlanta, of course.
I used to commute to jobs in Africa, and South America and Atlanta has always been my favorite airport.
Quit flying out of Miami, the worst in the USA, because it was such a rotten experience.
