On a smaller scale, but Indianapolis’ airport went through a similar transformation with their new terminal. It’s a medium sized airport with just one terminal but they built a new one in 2008 and tore down the old. I was on one of the first flights to come in to the new terminal, can’t remember if it was on the actual first day of operation or not. The old terminal felt like you were walking through an average high school building, nothing pleasant at all about being there. The new one is all about windows and open space and was also the first terminal fully designed and built after 9/11. It only has ~40 gates so it doesn’t have to deal with the massive operations or hub functions of other airports, but it still at the top of rankings for medium sized airports even 14 years later is by far my favorite airport to fly through.

Only bad experience I have ever had there was when I made the mistake of flying Allegiant. We got in and got off the plane, waited for luggage and it never came. Some people went to the Allegiant desk to ask what was going on eventually and found no one there. Turns out all of Allegiant’s staff left for the day and no one ever got the luggage off the plane. 🤣 Much funnier looking back.
