it is nothing less than incredible. Anyone that has traveled through Hartsfield-Jackson airport understands. They move so many people to so many different places it is easy to take for granted how effortless they make things until something goes wrong.
My only gripe is that I don't get free upgrades to what is now "Delta Comfort" seating. Luckily if the flight is long enough I have the ability to purchase the upgrade without much pushback from my employer.
Overall my experience has been pretty good.
