Flying from Seattle-Tacoma

The Link Light Rail Red Line runs from the airport's elevated station directly to Westlake in downtown Seattle in 38 minutes for $3.25 — possibly the easiest big-city transfer in the country.

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.
