DL used to have a lounge at LAS (which closed years ago). I specifically asked why they closed the lounge (admittedly DL has a small presence at LAS), and was told their lease was not renewed as part of an airport policy to eliminate lounges. Several other airlines have also closed their lounges at LAS in the past decade -- and it wasn't from a lack of passengers. During this time the airport has had extensive construction, with dozens of opportunities to open new lounges -- yet it hasn't happened. Name one airline lounge that has opened at LAS in this century. Lots of talk about it, but somehow it never gets done. The airport authority cannot ban lounges, but they can sure make it difficult.
