The Westcliff Airport Express is a new commuter express line the RTC launched December 2010. This is the first express bus service in and out of the airport in Las Vegas, you can catch the bus at Ground Level Zero. From McCarran, the bus goes directly to The Strip at Tropicana, hops on the freeway and then goes straight to Downtown Las Vegas/Fremont Street. If you are a local like me then this is really nice because from downtown you can ride directly to Summerlin with no stops in-between or switch to the Centennial Express and head up to the NW edge of town off Durango and US-95. In my opinion, this service is FAR easier to deal with than all the overpriced cabs and lame airport shuttles. You can catch the Westcliff Airport Express for just 2 bucks one way, $3 for a two hour pass, or $5 for an all day pass. Anytime I head to or from the airport I always leave my car at the Centennial Hills Park & Ride and take this express service down, it's easy, fast and ecomomical.
