It's been remodeled recently, I think, and it is Dire as a view of the future of airports. Most of the public seating has been removed in favor of a variety of lounges, which are airline-run and paid spaces to enter. They're big glassed-in spaces so you can see what you're missing as you walk by outside. The small amount of remaining pubic seating is far from the gates, overcrowded, and all the electrical outlets are broken. The rest of the space is an overpriced shopping mall, selling clothes and electronics and gifts. Masks and hand sanitizer are available in airport-priced vending machines.
It's gross and I hate the future.
