London to Detroit (LHR–DTW) — Airlines, Schedules & Connections

British passport holders enter the US under the Visa Waiver Program (VWP) for up to 90 days for tourism or business. You must obtain an ESTA (Electronic System for Travel Authorization) before departure. The ESTA costs $21, is valid for 2 years or until your passport expires, and allows multiple entries. Apply at esta.cbp.dhs.gov, the only official site. Most approvals come within minutes, but apply at least 72 hours before travel. The 90-day stay cannot be extended under the VWP.

Passport must be an electronic/biometric passport (all UK passports issued since 2006 qualify). You need proof of onward travel out of the US within 90 days. CBP officers at the port of entry make the final admission decision and can ask about trip purpose, accommodation, and ties to the UK. Automated passport control (APC) kiosks and Global Entry (for pre-approved travelers) speed up arrival processing. Anyone with certain criminal convictions, prior visa denials, or dual nationality with Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria, or Yemen may be ineligible for the VWP and need a B-1/B-2 visa ($185) from the US Embassy in London.

Direct flights from London Heathrow to New York (JFK) run about 7 hours 30 minutes westbound. Multiple US destinations have direct service from London, Manchester, and Edinburgh. The 90-day VWP clock does not reset by visiting Canada, Mexico, or the Caribbean and returning to the US; the original 90 days continues to count down. No vaccination requirements for UK arrivals. US Customs allows $800 worth of goods duty-free per person.

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.
