Madrid to Washington (MAD–DCA) — Airlines, Schedules & Connections

Spain is part of the US Visa Waiver Program. Spanish passport holders can enter the US for tourism or business for up to 90 days with an approved ESTA (Electronic System for Travel Authorization). Apply at esta.cbp.dhs.gov at least 72 hours before departure. The fee is USD 21. The ESTA is valid for 2 years or until your passport expires, whichever comes first. It covers multiple entries.

Your passport must be machine-readable and, for VWP travel, must be an ePassport (the kind with the chip symbol on the cover). Spanish passports issued after 2006 meet this requirement. The 90-day ESTA stay cannot be extended and cannot be changed to another visa status from inside the US. If you need more than 90 days, apply for a B-1/B-2 visa at the US Embassy in Madrid.

US border officers have wide discretion. Have your return flight, hotel address, and a general itinerary ready. ESTA approval does not guarantee entry. The CBP officer makes the final decision at the port of entry. Global Entry (USD 100, 5-year membership) speeds up arrivals significantly at US airports if you travel frequently.

Metro Line 8 runs from Nuevos Ministerios (central Madrid) to T1/T2/T3 in 12–15 minutes (€6, including the airport supplement). T4 requires an additional free shuttle from T2; add 10 minutes. The Cercanías commuter train (Line C-1) reaches T4 from Atocha station in 25 minutes (€2.60, no supplement).Taxis have a fixed fare of €30 from central Madrid zones. The ride is typically 20–35 minutes depending on traffic. Avenida de América bus hub serves several airport bus routes (€5).

The Metro station is inside Terminal B/C with covered walkway access; Terminal A requires a short outdoor walk or shuttle. Yellow and Blue line trains run to downtown DC in 15–25 minutes for $2.25–$3.85.

Taxis and Uber/Lyft operate from designated pick-up zones outside each terminal; fares to downtown run $15–30. DCA serves the National Mall area and is well-positioned for the U.S. Capitol, Pentagon, and downtown offices. International arrivals clear customs at DCA only for pre-cleared flights; most international traffic uses IAD (Dulles). Rental cars are in a consolidated facility accessible by shuttle.

Humid subtropical climate. Summers (June–August) are hot and very humid at 29–34°C with frequent afternoon thunderstorms causing ground stops and airspace flow programs. The summer storm season is the primary operational disruption risk at DCA. Spring and autumn are transitional with variable conditions and occasional severe thunderstorm outbreaks.

Winters (December–February) bring cold temperatures (−2 to 7°C) with occasional snowstorms that disproportionately affect the DC area due to limited snow-removal infrastructure. Even moderate snowfall (5–10 cm) can shut regional airports for hours. Pack layers for winter; the region's storm response is notoriously inconsistent.
