Harry Reid International Airport

Harry Reid International is the busiest origin-and-destination airport in the United States as a share of total traffic, a function of Las Vegas's position as the country's largest pure leisure-destination market. LAS serves 60 airlines on 462 routes to 218 nonstop destinations, handling over 57M passengers in 2024 with almost no connecting traffic — virtually every arrival is a Las Vegas visitor or resident, an unusual economic profile for an airport of its scale. Renamed in 2021 from McCarran International, the facility sits 8 km (5 mi) south of the Las Vegas Strip at an elevation of 2,181 ft (665 m). Southwest Airlines operates its largest crew base here; Spirit, Frontier, Allegiant, and Delta maintain substantial focus cities. The lack of a dominant hub carrier is itself structurally important: fare levels at LAS are among the lowest in the U.S. for top-50 airports, because no single carrier controls enough gates to pattern-price. Four runways arranged in two parallel pairs — the longest the 14,835 ft (4,522 m) 08L/26R, one of the longest commercial runways in North America — allow quadruple-independent operations and handle peak-weekend arrival rushes compressed into narrow Friday-afternoon and Sunday-evening windows. Two terminals — Terminal 1 (mostly domestic) and Terminal 3 (international and some domestic) — are linked airside by an automated people-mover connecting to the D Gates satellite concourse. Terminal 3's international arrivals facility handles nonstop flights from London, Frankfurt, Seoul, Tokyo, and seasonal European and Asian charters. LAS's proximity to the Strip is commercially unusual for a major U.S. airport — the elevation of the taxiway is directly visible from hotel-tower upper floors — and slot-machine concessions inside the terminal after security generated the original airport revenue-diversification model now widely copied elsewhere.
