I have in-laws in Vegas so i've been several times and of course with each trip I fly threw McCarran International Airport. Never a problem. Very well organized as far as security and signage. The staff there is incredibly friendly. On my way back this last trip I sat next the check in desk at our gate and the staff handled each group that came up with patience like I've never seen before. They even managed to turn some customers that seemed to have a stick up their ass*s attitudes around due to their friendliness. Gotta love good customer service.
