London Heathrow Airport: The Ultimate 3-7 Hour LHR Layover Guide (by a pilot)

One of my favorite short layovers ever: London Heathrow (LHR). Amazing lounges, easy and efficient public transportation, and endless options to eat/sleep/dine/explore. You can always count on London being a great layover.

Coming Up:

As the busiest airport in the UK, Heathrow offers a vast array of international flights and fantastic connections on over 80 airlines. This means you will likely have the chance to try it out for yourself someday! But don’t worry – whether you have a 3, 4, 5, 6, or 7 hour layover in London, there is a lot you can do to have fun.

As an airline pilot flying internationally from New York’s JFK airport, I normally layover in London multiple times per month. Here’s a little foreshadowing, if I haven’t made it obvious already: I love it. It’s an epic city.

And for those not looking to leave Heathrow airport, fret not – the lounges, restaurants, and terminals are world class. You just have to know where to go.

Should I leave London-Heathrow Airport (LHR) on a short layover?

Exploring the London Tower is one of my best layover memories!
I always love to go out and explore London. But having enough time in a layover depends on many factors.

That depends. There are many factors in play:

  • Is it a Thursday, Friday, or Saturday? These are busy days and security lines will be longer.
  • Are there planned strikes by public transportation workers or taxi workers? These are usually announced ahead of time and cause massive delays.
  • Is the weather bad enough to create chaos with cancellations, delays, and rebookings?
  • Are you arriving on an international flight? Do you need a visa to enter UK territory? If so, going through customs may add time. (US passports are eligible for entry through fast-lane visa-free passport scanners, saving ample time)
  • Do you have bags to collect and check back in? Check-in lines could be long, though you can save time by checking them in at a transfer desk before exiting the secure zone.
  • Are you arriving at night? This may call for a short hotel layover instead of going out and exploring.
  • Do you have Priority Pass and less than 4 hours before your connecting flight? If so, it may make more sense to spend your layover at an excellent free lounge.

This summer is extremely busy, and airports and airlines are suffering from short staffing. Because of this, you can expect long lines at check-in, security, help desks, and more. Plan extra time for this.

What you can do inside London Heathrow International Airport on a layover

The only real outdoor terrace at London Heathrow is located in the Virgin Atlantic clubhouse of Terminal 3.
A well kept secret at LHR: the outdoor terrace of the Virgin Atlantic Clubhouse! My favorite.

For those who prefer not to leave the airport, fret not – there’s a lot to do.

You have 6 terminals to chose from, each offering an array of restaurants, shops, and lounges. Many of these lounges offer free access for Priority Pass members, while others are reserved for business/first class fliers and members. Check below.

Some of the restaurants here are world class, and there’s everything from delicate sushi to fried chicken to feast one.

Many of the lounges have excellent wining and dining, showers, and even spas. The Virgin Atlantic Clubhouse has a wonderful outdoor terrace, while the No1 Lounge has a separate TV Lounge room.

And if you really want to get some exercise, there’s miles of corridors and hallways to explore. If your terminal isn’t enough, it’s super easy to take a bus to another one, though you will likely have to pass through security again if you do.

Best LHR Lounges (and what you need to know first)

The Lounges at Heathrow are excellent and provide a great place to pass time on a layover.
A freaking pool table! Though the No1 Lounge is my favorite PriorityPass lounge, the Virgin Atlantic Clubhouse is the best option for members and business class fliers.

Most of the lounges at LHR Heathrow are excellent, and some are even world class. Take the Virgin Atlantic Clubhouse for example, boasting everything from Peloton bikes to an outdoor terrace – with champagne and fine dining in between. I prefer it over even the flagship KLM Crowne Lounge in Amsterdam!

Priority Pass members can rejoice – there are several wonderful lounges included for free! The No1 Lounge, for example, features a spa, showers, movie theatre, and a very diverse bar. At this time, the showers are still not operating.

Pro Tip: the No1 Lounge is the best Priority Pass Lounge in Terminal 3. As such, it fills up quick. Make sure to pre-book on the Priority Pass app for 6£ and reserve a spot.

AmEx Platinum members have access to the world-renowned Centurion Lounge in Terminal 3, with top notch fare and a comfortable, but slightly cozy environment.

Right now, PriorityPass is offering up to 25% off yearly memberships. In just two lounge visits, you are already ahead vs. paying for one-time access. Just one if you bring a guest!

Lounges at LHR included with Priority Pass

The No1 Lounge Heathrow is an excellent complimentary PriorityPass lounge.

As a benefit to Priority Pass members, Terminal 3 is home to both the Club Aspire Lounge and the No1 Lounge Heathrow complimentary. Both are excellent complimentary options.

Those transiting Terminal 5 can enjoy yet another excellent Club Aspire Lounge.

Lounges at LHR that allow purchase of a day pass

Unless you’re flying in business or first class, you might be worried about finding a nice lounge to relax in between flights. But luckily, most terminals at LHR have at least one lounge that allows purchasing of a day pass.

Here they are, with their respective prices (which may not be 100% up to date):

Terminal 2:
  • Plaza Premium Lounge (£40/3 hours, £65/6 hours)
  • Lufthansa Business Lounge ($74)
  • United Club ($59)
Terminal 3:
  • No1 Lounge (£36 online)
  • Club Aspire (£35 online)
  • American Airlines Lounge ($59, currently closed)
Terminal 5:
  • Club Aspire (£40 online)
  • Plaza Premium (£35/3 hours, £65/6 hours)

Exclusive airline lounges

The Virgin Atlantic clubhouse is one of the best lounges not only at Heathrow, but in general.
I recently visited the Virgin Atlantic Clubhouse, and found it was one of my favorite – ever!

Air Canada, American Airlines, British Airways, Lufthansa, Qantas, SkyTeam (T4), and United all have their own respective lounges. Most of these are reserved for business and first class passengers, but some offer paid options for those flying in economy or comfort.

There are typically also yearly options available for those who travel constantly (and always with the same airline(s).)

The Virgin Atlantic Clubhouse in T3 is particularly worldly, offering multiple restaurants, peloton bikes, showers, a pool table area, and even an outdoor patio with epic views of LHR. Those flying business class on Virgin Atlantic and SkyTeam partners have access.

Catch some sleep at an LHR Day Room

The Aerotel Hote at Heathrow is the only hotel located in arrivals, saving valuable time on a Short layover.

Though there are no hotels inside the secure area at Heathrow Airport (which means you’ll have to exit and go through customs/security), there are some on or near the airport that offer day rooms.

Day rooms are my newest dangled “travel hack”, because there’s nothing more refreshing than catching up on rest and taking a shower between flights. They’re actually my biggest travel hack to beating jet lag.

The best day rooms around LHR include:

  • The Aerotel in T3 arrivals, which offers blocks of 3, 6, and 9 hours.
  • The Hilton Garden Inn Terminals 2 & 3, step away from arrivals. Note there is another Hilton Garden Inn on Bath Road.
  • Next to Terminal 4, you can stay at the Heathrow Hilton or the Premier Inn just a touch further.
  • By Terminal 5, there’s a Sofitel connected by a covered walkway. The Sofitel is for sure the nicest Heathrow area hotel.
  • The Hilton Garden Inn, just steps from Hatton Cross, one stop away from Heathrow on the Picadilly line.

These hotels and many others offer shuttle service. My personal best way to snag a cheap room is on

Going out and exploring on a short Heathrow layover

Little Venice is a hidden gem to explore on your next London layover.
Little Venice, one of my favorite lesser known places for a stroll in the gorgeous town of London. Great on a layover.

Even after having traveled to over 80 countries, I still have to contend that London is one of my favorite cities. And excellent public transport makes it one of the most accessible cities in the world, even on a short layover.

You have so many options on places to go and how to get to them – you can tailor your layover to any level of exploration. I’ve found that even after many, many layovers, London just does not get old. There’s always more to do.

So whether you see a lot or a little, you’ll be glad you did. Here are my recommendations on what to do during your London layover.

Getting to downtown London from LHR – quick!

The Heathrow Express is probably the best way to maximize a short London Layover!

Buckingham Palace, Hyde Park, Piccadilly Circus, Harry Potter. Whatever your rhyme or reason is for visiting London, you’ll be glad to know there is a fantastically fast way to get downtown from LHR airport.

It’s namely the Heathrow Express, offering direct service to downtown with a journey time of about 15 minutes. Though it’s more expensive than the tube (metro/underground), I highly recommend it. The underground/tube often has delays and many stops, making it a much more tedious way to get to London from LHR.

The fare for the Heathrow Express is normally 25£ one way and 37£ return (roundtrip), but here’s a little secret - if you book ahead, you can get fares as low as £5.50 each way!

Renting a car for the day and going more in depth

Though public transportation in London is excellent, you may prefer the flexibility of having your own car. This unlocks the ability to see even more of the area, including:

  • The Royal Observatory of Greenwich, located at the Prime Meridian (0 degrees longitude)
  • Oxford University and its Museum of Natural History
  • The Windsor Castle
  • The incredible Brooklands Museum, featuring everything from rockets to the Concorde
  • With more time, the coast of Brighton

In my experience, Hertz offers the most reliable and convenient rentals.

I tend to prefer Hertz as a rental car company for their simplicity and ease of use

Just beware of parking downtown, which is mighty inconvenient and expensive.

Join a free (or cheap) guided tour of the city

London is easily one of the most walkable cities in the world. I would know – I’ve walked close to 100 miles around the city.

But to really learn about the history, culture, and hidden gems of the city, I highly recommend a guided tour – especially if you’re in a hurry.

Otherwise, here’s a sample itinerary I curated for your viewing pleasure:

Some of the sites you won’t want to miss include:

  • Buckingham Palace – you can even visit a State Room from 22 July to 2 October and some dates in winter! Changing the Guard, an amazing show, occurs most days at 10:45AM
  • Go shopping in the historic area of St. James.
  • Hit up Westminster Abbey. Don’t miss out on that giant clock tower they call Big Ben somewhere around there.
  • Visit Churchill’s War Rooms for a chilling and enlightening experience
  • Ride the London Eye for epic views of the city
  • Walk through SoHo and experience London’s most vibrant neighborhood
  • Tour the 900-year old Tower of London and learn about the medieval history of the city
  • Take an elevator to the top of the Tower Bridge
  • Head up the the observation deck at The Shard, that pointy building that rises high above the city skyline

Each of these sites is located near an Underground (Metro/Tube) station, and the order listed above is a good way to do it. Note that it would probably take an entire afternoon (4-6 hours at least) to see all of that in a hurry, so you’ll have to pick and choose.

An excellent option to maximize a short layover would be taking a top-rated Hop On, Hop Off Bus in London.

Eat local, classic British fare

Enjoying local British food is one of many must-dos on any London layover
I’ve been known to frequent the Mayfair Chippy, a Michelin star rated fish n’ chips locale. Totally possible on a short Heathrow layover.

Fish n’ chips, a nice meat pie, bangers n’ mash, Shepherd’s Pie – all nice boring British food for you to try.

The Indian food is where it’s really at. Let’s bring the spice and the taste. There’s no lack of great Indian food here.

My favorite Indian place? Dishoom, a local favorite with several locations across town, is flabbergastingly good. Probably the best in London.

For a great fish n’ chips, the Mayfair Chippy is your spot. And for a local chain with fantastic fare, try The Ivy.

If you want to eat at one of Gordon Ramsay’s excellent dining experiences, make sure to book ahead.

And lastly, great coffee is everywhere. For a unique experience, try Attendant Coffee Roasters, situated in what used to be a Victorian public toilet.

Getting back to Heathrow on time for your next flight

In recent years, we’ve experienced unparalleled travel chaos. That meant dealing with travel disruptions such as delays, cancellations, late bags, and more.

Luckily, staffing is already better as of 2023 and it’s only improving from here.

That being said, you should still plan to arrive at the airport 2-3 hours before any international flight and 1.5-2 hours before a domestic flight. Whether you use an Uber, rental car, the tube, or the Heathrow Express – always plan in extra time.

Best of luck with your London travel plans!
