I had the pleasure of flying into Terminal 3 at McCarran International Airport in Las Vegas and can I say what an upgrade!! I did not have to take that tram. Everything is brand new with free reliable WiFi, I watched a few Crackle episodes of "Comedians In Cars With Coffee" while I waited for a flight out. There is helpful signage and a dedicated valet level and area for Ride Share pickup. The rest room facilities are clean and well maintained and plentiful. I was happy the TSA line moved smoothly and quickly. I was very happy there were clean, modern water fountains in the boarding area. The seats and electrical outlets and charging sections were plentiful.
