Detroit to London Heathrow Flights (DTW to LHR): Delta Nonstop, Flight Time and Entry Rules

Yes, Detroit has a daily nonstop to London. As of recent schedules, Delta flies from Detroit Metropolitan (DTW) to London Heathrow (LHR) every day, and Virgin Atlantic sells seats on the same flight under its joint venture with Delta. The eastbound flight takes about 7.5 hours; the return takes about 8.5 to 9. Check the current schedule with the airline before you book.

Who flies Detroit to London

The nonstop: Delta, with Virgin Atlantic

Detroit is one of Delta's main hubs, and Heathrow is one of its core European routes from there. Delta operates the aircraft; Virgin Atlantic, Delta's transatlantic partner, sells the same flight under its own flight number. That means you can book through either airline, earn miles with either programme and land in London in the same terminal as Virgin's own flights. Check the "operated by" line when you book, because the service and the airline's app are Delta's either way.

One-stop options

If the nonstop is full or the fare is high on your date, one-stop itineraries are easy to find:

• Delta and Virgin Atlantic through Atlanta, New York JFK or Boston.
• American with British Airways through Chicago, Philadelphia, Charlotte or New York JFK.
• United through Newark, Chicago or Washington Dulles.
• Air Canada through Toronto, a short hop across the border.

A connection usually adds three to five hours. London has six airports and some connecting tickets land at Gatwick, so check the airport code before booking a transfer. For help choosing, read nonstop vs connecting flights.

Flight time and distance

DTW and LHR are roughly 3,750 miles apart. The eastbound nonstop is an overnight flight of about 7.5 hours with the jet stream behind it, landing in London the next morning. The westbound return is a daytime flight of about 8.5 to 9 hours that reaches Detroit the same afternoon or evening.

London is five hours ahead of Detroit for most of the year. The US and UK change clocks on different dates, so the gap drops to four hours for a couple of weeks in March and again around late October and early November. Eastbound you lose a night: sleep as much as you can on board, get daylight on arrival and stay up until a normal London bedtime.

Departing from DTW

Delta, its regional partners and its SkyTeam partners use the McNamara Terminal; almost every other airline uses the Evans Terminal, a shuttle ride away. The London flight leaves from McNamara, which has Delta Sky Clubs and its own international arrivals hall for the trip home. If your connecting itinerary is on United, American or Air Canada, you will start at Evans instead, so check the airline before you set off. Allow about three hours for an international departure, as the counter checks your passport and UK ETA.

Arriving at Heathrow and getting into London

Delta and Virgin Atlantic share Terminal 3 at Heathrow as of November 2026. Heathrow has decided to move Delta's operation to Terminal 4 in 2028, and Delta has said it will challenge that decision, so check the terminal on your booking close to departure. UK Border Force lets US passport holders use the e-gates, so immigration is usually quick, although the morning transatlantic bank can still build a line.

Heathrow is about 15 miles west of central London, and the rail links are the best way in:

• Elizabeth line: from every terminal to Paddington in about 30 minutes, then straight on to Bond Street, Liverpool Street and Canary Wharf without changing. The best value for most central hotels.
• Heathrow Express: nonstop to Paddington in about 15 minutes. The fastest option and priced accordingly; booking ahead is cheaper.
• Piccadilly line: the Underground reaches the West End in roughly 50 to 60 minutes and costs the least. Fine with light bags, slow with heavy ones.
• Taxi or car service: 45 to 90 minutes depending on traffic, and expensive for the distance.

Tap a contactless bank card or phone at the gates. London caps daily fares automatically, so there is no need to queue for an Oyster card.

Entry rules for US citizens: get the UK ETA first

US passport holders need a UK Electronic Travel Authorisation (ETA) before they fly to the United Kingdom. You apply in the official UK ETA app, which scans your passport and your face, or on GOV.UK with photos of both if you cannot use the app. Most people get a decision by email within a day, but GOV.UK says it can take up to three working days, so do not leave it to the night before. There is a small fee; check the current amount on GOV.UK and avoid look-alike sites that charge more.

The ETA is linked to the passport you applied with and lasts two years or until that passport expires, whichever comes first, with as many trips as you like in that time. It covers visits of up to six months. The airline checks for it at check-in in Detroit, and without it you can be refused boarding. Our UK ETA guide for US travelers walks through the application step by step. If you continue to Ireland, note that Ireland is a separate country with its own entry rules and does not use the UK ETA.

Best months to fly to London

June to August is the busiest stretch, with the fullest flights and the highest fares. Easter, the late-May school break in England and the Christmas and New Year period are also strong. May and September are the sweet spot for many travellers: long days, green parks and fewer crowds than midsummer.

January, February and November are usually the quietest months and the easiest for a good fare, with short grey days but full theatres, museums and pubs. Detroit's winter makes a London city break in January or February more appealing than it sounds: London is milder and rarely sees snow. For summer, start watching fares four to six months out; for the quieter months, six to ten weeks ahead is usually enough.

Because the nonstop runs daily, flexibility on the day of the week often matters more than on rarer routes. The fare grid on this page shows live options for your dates.

Baggage and fare families

On Delta, Main Cabin fares to Europe typically include one checked bag of up to 23 kg, while Basic Economy may include none. Virgin Atlantic's Economy Light includes no checked bag and its Economy Classic includes one. Because Virgin sells this flight but Delta operates it, check the allowance printed on your ticket rather than assuming the operating airline's rules. Allowances change without much notice; see our Basic Economy explainer before choosing the cheapest fare.

Coming home

The return lands at DTW's McNamara Terminal, where US Customs and Border Protection clears arriving passengers. Global Entry members can use the kiosks; if you travel abroad more than once a year, our Global Entry vs TSA PreCheck guide helps you decide whether it is worth it.

Common mistakes on this route

Leaving the UK ETA until the airport is the most common one. The next is assuming Heathrow terminals are next door to each other: Terminal 3, Terminal 4 and Terminal 5 are a train ride apart. And many people pay for the Heathrow Express when the Elizabeth line goes further into London for much less.
