Madrid to Detroit (MAD–DTW) — 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.

DTW has no rail. Ride-shares and taxis are the practical options. Taxis to downtown cost $45–60. Ride-shares run $30–45. The two terminals (McNamara and North) are connected by the automated people mover (MTC); both share the same baggage claim and ground transport facilities.Car rental desks are in the consolidated facility accessible from McNamara Terminal. SMART bus Route 261 serves the airport with transfers into the bus network. Allow extra time for I-94 congestion during peak hours.

Humid continental climate. Winters are cold and snowy (−8 to 0°C) from December through March. Lake Erie and Lake St. Clair generate significant lake-effect snow that can fall heavily with little warning. Ice storms and blizzards cause the most serious flight disruptions.

Summers are warm and humid (26–32°C) with frequent afternoon thunderstorms. Spring and fall are transitional with frost risk into April and from October. January and February are the highest disruption-risk months.
