Las Vegas is served by McCarran International Airport (code: LAS), 5757 Wayne Newton Blvd., just a few minutes' drive from the southern end of the Strip, where the bulk of casinos and entertainment venues are concentrated. The airport is about 2 miles away from the conference location, the UNLV student union. Most hotels in the area have airport shuttles connecting LAS to/from the hotels.
Most major domestic and many international airlines fly into Las Vegas, and the city acts as a major routing point for low-cost Southwest Airlines. The airport has two terminals. Terminal 1 serves mostly domestic carriers with four sets of gates. A and B gates are accessible to the main ticketing area and baggage claim by (very long) hallways, while most of the C and all of the D gates are reached by tram. The ultramodern Terminal 3 opened in 2012 and primarily services international and some domestic carriers like United with its 14 gates. Each terminal has its own baggage-claim facility and services such as dining, shopping, and traveler assistance, along with ground transportation areas for taxis, hotel shuttles, buses, and shuttles to the rental-car facility. And yes, all of the terminals and baggage claims have slot machines just in case you want to lose a few bucks while you're waiting for your luggage ☺
