At the United Terminal LAS Vegas Airport, there are precisely 110 gates for aircraft spread across two terminal buildings: Terminal 1 (also known as T1) and Terminal 3 (also known as T3). Each of the two terminals has its own parking space, baggage claim area, ticketing area, dining area, and retail establishments. Because there is no connection between the two terminal buildings, it is essential for all travelers to know which airline serves which terminal before arriving at the airport.
