About this corridor

Flying from San Diego International

San Diego International is the busiest single-runway commercial airport in the United States, sitting 3 miles from downtown San Diego. MTS Route 992 runs from the terminals directly to downtown in around 15 minutes for $2.50; the future Trolley extension (planned 2027) will provide direct light rail. Southwest and Alaska have the largest schedules; American, Delta and United add full-service capacity. Limited international long-haul — British Airways and Lufthansa serve London and Frankfurt direct.

Arriving in Las Vegas

Las Vegas's Harry Reid International is 5 miles south of the central Strip — a five-minute taxi ride to most resorts. There is no rail; the airport shuttle, taxis, monorail-shuttle hybrid and rideshare handle the volume. Convention-week demand spikes (CES in January, NAB in April, Magic Apparel in February) push fares 2–3× their normal levels. Tuesday and Wednesday departures and arrivals are routinely the cheapest.
