I think folks like us who couldn't travel for about 18 months are making up for lost time, so everything is crunched today, all of it, security lines, rental cars, gate agents, full planes, I'm more amazed it works as well as it does than anything.
We're lucky not to have to drive much, my wife drives to pilates and that is problematic but only 3 miles or so. I tend to forget how bad traffic is until I have to drive someone to the airport. It's a $35 taxi fare, more for Lyft/Uber most of the time. We pay $0.70 per ride on MARTA which takes about 25 minutes to walk to a station and then 25 minutes to the airport. My wife doesn't care for it, but ....
We take the taxi if we're headed to Europe and have a ton of luggage.
Expanding MARTA would help, but the outer counties don't want it, and it's expensive to build more of course.
