Uber is now fully authorized in Las Vegas, recently gaining approval to operate at McCarran International Airport.
It's been a long journey for Uber to get to Las Vegas. The service was banned, then briefly operated, and banned again before gaining approval first to operate outside of tourist areas, then moving into the resorts and now airport.
I've long thought that Uber, while a great service is somewhat unnecessary in Las Vegas. Taxicabs (annoying long hauling aside) are available everywhere so it's usually not a problem getting around.
That being said Uber has gained so much popularity in such a short amount of time that it's become the default mode of transportation for many people. It's very possible that young people in Las Vegas won't even consider cabs since they are so used to using Uber.
