The boarding process is still chaotic and unorganized. I love the “lines” in the Atlanta airport with the different boarding levels. Makes everything more organized. For a long flight, over 4 hours, more refreshments could have been added. There should be an enforced limit on how much carry on luggage a passenger can take.
