My favorite thing is the "silent terminal" concept. Most major airports if you arrive groggy at 5am waiting for your flight, you are blasted with a bunch of nonsense announcements that have nothing to do with your flight every 2-5 minutes "Keep your baggage with you at all times" "The USO is located...", etc. and in between the announcements loud music gets played. Trying to find a location away from a speaker is no good because there are speakers in the ceilings about every 10ft in a grid. It surprised me when i visted SFO terminal 1 how much a quality of life improvement it is to just have silence in a public place.
