Just took my first flight since the pandemic started. Flew to Las Vegas last Wednesday and returned home last night.
Contrary to some of the horror stories about flights, and passengers, both flights were actually pretty calm, even orderly. No one was getting told to wear their mask in the airports or on the planes. When the gate agents asked everyone to stay seated until their rows were called, pretty much everyone complied, contrary to my experience before covid.
There were a fair number of people in Las Vegas, but I wouldn't call it over-crowded at all. Most employees at the casinos and restaurants were wearing masks full time. Most tourists were not.
I will say that they must be selling tons of weed in Nevada because it was pretty tough to walk anywhere outside along the strip and not get a contact high. That was maybe the biggest change I noted.
Also pretty obvious they are having problems finding employees. Even though there were quite a few people in the casinos, a lot of table games without dealers, a lot of bars and restaurants running short staffed, etc...
Edit: There was one surprising incident at the Las Vegas airport, though. The security line that I was in suddenly came to a stop. I was trying to figure out why when a handful of additional TSA agents showed up. They were talking to a guy about his backpack. They then opened it up and pulled out a knife with about a five inch blade. One of the TSA agents looked at the guy and said, "seriously dude, you thought this was ok???" Jeebus, what was that guy thinking.
