Flying from Reagan National
Ronald Reagan Washington National sits 4 miles from the Capitol — one of the most central airports in the United States, with strict perimeter rules limiting most non-stop flights to within 1,250 miles. Metro Yellow and Blue Lines run from the airport's own station directly to downtown DC in 8 minutes for around $2.50. American and Delta have the largest schedules; nearly all flights are domestic. The strict perimeter and slot controls keep DCA fares structurally higher than IAD or BWI.
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.
