Granada to Dallas-Fort Worth (GRX–DFW) — 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.

DART Orange Line runs to downtown Dallas (50 min, $3). TEXRail reaches downtown Fort Worth in 55 minutes ($2.50). Taxis and ride-shares cost $25–45 to either city center.Rental car facilities are at the south end. All terminals connect via the free Skylink train; this is an airside-only connection, so you must clear security first to use it.

Hot continental climate. Summers are intensely hot (35–40°C) with little rain. Winters are mild (3–12°C) but ice storms hit 2–3 times per year, causing major airport disruptions.

Spring (March–May) brings severe thunderstorms and tornado risk that regularly ground flights. Fall is the best travel window with moderate temperatures and low storm frequency.
