London In A Weekend
Key Takeaways
- A weekend trip to London from the US can be affordable and quick, especially from the East Coast.
- Flights often cost under $500, and travel time can be shorter than flying within the US.
- Utilize Google Flights for booking and consider frequent flyer programs for potential upgrades.
- Heathrow Express offers the fastest transfer to central London; booking in advance saves money.
- Pack light and be ready for varying weather; three days is enough to see major attractions.
If you think a weekend in London means expensive flights, complicated planning, and taking a week off work, think again. This is a quick guide to show you how easy (and surprisingly affordable) it can be to hop across the pond for just a few days. From the East Coast, you can be sipping tea in Covent Garden or strolling along the Thames in less time than it takes to fly to California.
London: A Quick, Affordable Escape Across the Pond
London, England, The United Kingdom of Great Britain and Northern Ireland.
Most just call it London (so do I, I like just being humorously exact sometimes). London is one of my wife’s and my favorite cities to visit for fun.
Living on the East Coast of the United States, it can actually be quicker to fly to London than to parts of the western U.S. For example, Delta shows a Boston–San Francisco flight at 6 hours 53 minutes, while Boston–London is just 6 hours 35 minutes. Coming back takes longer, but you get the idea.
Also, flights are often much cheaper than people expect, sometimes under $500. Using Google Flights, I’ve even seen fares under $400 if you book ahead. Smaller airports may cost more (Jacksonville, Florida, for example, was around $600 with a stop in Charlotte), but it’s rarely the “thousands of dollars” people imagine for Europe.
How London Fit into Our Travels
My first trip to London came during a week-long adventure split between there and Berlin, Germany. London was on the list simply because we wanted to visit, and Berlin because my wife’s cousin was running the Berlin Marathon.
About a year later, we returned to London for the same cousin’s London Marathon run. She’s both crazy and amazing! This post is about that second trip, which was shorter and more organized. (The Germany/London trip will get its own story later.)
Booking the Trip
Every trip starts with booking, and for me, that almost always means Google Flights. I try to fly Delta whenever possible because:
- I earn most of my miles there
- I have their premium credit card
- I hold high status with them
That said, I’ll choose a good deal over loyalty, and this time, Delta was still the best option out of Boston (my home airport at the time). I booked with miles, which was a great redemption, and used one of my Delta Global Upgrade Certificates (earned with Diamond status) to move from economy to Premium Select at no extra cost, about a $5,000 upgrade.
Our itinerary:
- Depart Boston: Friday 7 PM → Arrive London: Saturday 7 AM
- Depart London: Tuesday 10 AM → Arrive Boston: Tuesday 12 PM
That gave us three full days in the city.
Airport Tips
Most airlines recommend arriving 3–4 hours early for international flights. If you’re not checking a bag, have TSA PreCheck, or CLEAR, you can shave time off:
- No checked bag: save ~30 min
- PreCheck: save ~30 min
- CLEAR: save ~15 min
We had all three, so we arrived about two hours before departure. Terminal E at Boston can get hectic around 5 PM, but check-in was quick.
Bonus: At the gate, we got another surprise upgrade, this time to Delta One (lie-flat seats in private suites). This would normally cost $8,000+, but frequent flyer perks made it free.
The Flight
Once settled, the pilot came on with a friendly welcome:
Gooooooooood evening from the cockpit and thank you for flying Delta Air Lines flight 58 to London… smooth ride over the Atlantic tonight… may have a few bumps as we cross over Ireland…
I slept most of the flight, and we landed on time at Heathrow.
Heathrow & Getting Into London
Customs at Heathrow is straightforward, but getting to the customs hall can be slow due to multiple overnight flights arriving from the Americas. Once through, you’ve got three main ways into the city using public transit:
- The Tube – About 1 hour, cheapest option
- Elizabeth Line – Faster and more comfortable, slightly more expensive
- Heathrow Express – My favorite. Non-stop to Paddington in 15 minutes, as low as £10 if booked ahead (the most expensive last minute option)
Downtown London
London is… well, very London-like. Busy, loud, bright, and beautiful. Yes, it rains, but far less than most people think, NYC gets 117% more total rainfall than London each year.
From Paddington, we took the Elizabeth Line to Tottenham Court Road and walked to The Edition London (paid with Marriott points). At check-in, we were offered tea, which we gladly accepted.
Fun fact: In 2023, more Brits reported drinking hot coffee regularly (63%) than tea (59%) for the first time in history. Source
Touring & The Marathon
Our first day included a quick historic double-decker bus tour, lunch, and drinks at a busy pub. My wife’s cousin is chasing The Six World Marathon Majors (NYC, Boston, Chicago, London, Berlin, Tokyo)—Tokyo is the only one left for her.
The next day was the marathon, and I’d mapped the best viewing spots using the Underground. She scored us finish line tickets, which made for an incredible experience, though she finished injured, she still crossed the line.
Wrapping Up the Trip
On our final day, the runners headed to Ireland while we moved to the Hilton London Hyde Park for the night. Google calls it a 4-star, maybe a stretch, but the location made it easy to take a direct morning train to Heathrow, far more convenient than staying near the airport.
Experience London Differently
I’m typically not a tour person, but this vintage open-top bus tour was an exception. Historical, interesting, and perfectly paced for those who want to see London without the usual tourist rush.

Frequently Asked Questions: Weekend Trip to London From the US
A 3-4 day weekend trip to London from the US is ideal. The best strategy is to leave Friday evening from the East Coast, arrive Saturday morning, and return Tuesday afternoon. This schedule gives you three full days to explore London without needing to take vacation time from work, and you avoid severe jet lag since you sleep on the overnight flight.
A weekend trip to London from the US typically costs $1,200-2,000 per person. This breaks down to: flights ($400-600 round-trip when booked in advance), hotels ($150-300 per night for 3 nights), Heathrow Express ($20-50 round-trip), meals ($50-100 per day), and attractions ($50-150 total). Budget travelers can do it for under $1,200, while those seeking comfort might spend closer to $2,500.
Not at all. From East Coast cities like Boston or New York, London is only 6-7 hours away—shorter than flying to California. The direct overnight flight means you arrive Saturday morning ready to explore. The 5-hour time difference is manageable for a long weekend, and you’ll adjust naturally without needing recovery days.
Book your weekend trip to London 2-3 months in advance for the best deals. The cheapest months are typically January-March (except holidays) and September-November. Use Google Flights to track prices and set alerts. Flights under $500 round-trip are common during off-peak periods, while summer and December can push prices over $1,000.
The Heathrow Express is the fastest option, reaching Paddington Station in just 15 minutes for as low as £10 if booked online in advance. The Elizabeth Line is slightly slower (30-40 minutes) but more affordable and connects to more destinations. The Tube takes about an hour and is the cheapest option. For a weekend trip, the time savings of Heathrow Express make it worth the extra cost.
Yes! Three full days in London is enough to see major highlights including Buckingham Palace, Tower of London, Big Ben, Westminster Abbey, Borough Market, several world-class museums (many are free), and experience the pub culture. You won’t see everything, but you’ll get a genuine London experience and can always return for deeper exploration.
US citizens don’t need a traditional visa, but as of January 8, 2025, you must obtain a UK Electronic Travel Authorization (ETA) before traveling to London. The ETA costs £16 (approximately $20) and is valid for two years or until your passport expires, whichever comes first. It allows multiple visits of up to six months each.
Apply for your ETA online through the official UK ETA app or the GOV.UK website at least a few days before departure—most applications are approved within hours, but it can take up to three working days. You’ll need a valid passport (with at least 6 months validity), a digital photo, and payment. Airlines check for ETA approval at check-in, so you cannot board without it.
The ETA is similar to the US ESTA system and is not a traditional visa—it’s a digital travel authorization. If you’re planning to work, study long-term, or stay more than six months, you’ll need an actual visa instead.
Pack light for a London weekend trip—carry-on only if possible. Essentials include: layers (London weather changes quickly), comfortable walking shoes, a compact umbrella, power adapter (UK uses Type G plugs), and a light rain jacket. Don’t overpack—you’ll only need 2-3 outfits for a long weekend. London is casual, so leave fancy clothes at home unless you have specific dinner reservations.
The 5-hour time difference is manageable. Taking the overnight flight Friday helps since you sleep during the flight and arrive Saturday morning London time. Stay awake until at least 8-9 PM local time on your first day, even if tired. By day two, you’ll feel mostly adjusted. The return flight lands around noon US time, making the adjustment back easier.
