Travel Essentials
FRA: CET · IAH: CDT
When it's 6:00 PM in Frankfurt am Main, it's 12:00 PM in Houston.
German passport holders travel to the United States under the Visa Waiver Program (VWP) for stays up to 90 days. You must apply for ESTA (Electronic System for Travel Authorization) at esta.cbp.dhs.gov before departure. ESTA costs USD 21, is valid for 2 years, and approval usually comes within minutes. Apply at least 72 hours before travel in case of delays.
ESTA requires a machine-readable passport. If your German passport was issued after 2005 it qualifies. You need a return or onward ticket. The 90-day limit is strict and cannot be extended. Leaving to Canada, Mexico, or the Caribbean does not reset the clock. If you overstay even by one day, your ESTA is voided and future entries require a full visa interview at the US Embassy.
CBP officers at the US port of entry make the final admission decision. They may ask about your travel purpose, accommodation, and ties to Germany. Honest, brief answers work best. Global Entry membership (USD 100, 5-year validity) speeds up the arrival process at most major US airports through automated kiosks.
S-Bahn lines S8 and S9 run from Frankfurt Hauptbahnhof (main station) to Terminal 1 every 15 minutes (15 min, €5.65 single or included in a Frankfurt day ticket). ICE and IC long-distance trains serve the airport's own long-distance station (Fernbahnhof); this is separate from the S-Bahn Regional station and connects Frankfurt to Cologne, Stuttgart, Munich, and other cities without requiring travel through the city centre.Taxis from the city centre cost €25–35 and take 15–25 minutes. Terminal 2 connects to Terminal 1 via the free SkyLine people mover.

Terminal D handles international arrivals. Rental car agencies are in a consolidated facility adjacent to Terminal C; a free IAH Connector bus runs between terminals and the rental car center. The Galleria / Uptown area costs $35–50 by ride-hail.
Humid subtropical climate. Hot, humid, and wet for much of the year. Summers are brutal (33–38°C) with high humidity and near-daily afternoon thunderstorms. Severe storms with hail and high winds regularly cause ground stops from April through September. Houston's flooding risk is significant. Heavy rain events, including tropical system remnants, have flooded airport roads, cutting off surface access even when the airport itself remains operational.
Winters are mild (5–18°C) with occasional ice storms. These are rare but highly disruptive when they occur. Hurricane season (June–November) requires monitoring for Gulf storms. October through March has the best flying weather.
