8 hour morning layover in London

What is your final destination?

Unfortunately, you don't have as much time as you may think. It is close to a sucker play. Depending on where you are coming from you may have to go through immigration and customs prior to exiting the airport. So you could easily lose an hour and half to two hours just to get center London -- 8.15. Pretty early and some limitation on what is open. If you 8 hour layover means a 2.15 departure you need to be back at the airport by at least noon just to get through exit immigration and security (assuming you have your boarding pass) so that means you need to leave the London area around 11.15. So at best your have maybe three hours. Hardy time to see anything. Hampton Court is fairly close to the airport so maybe the best idea is to take a taxi to H court.

You may want to consider Windsor. It's about 20 minutes from Heathrow airport, certainly has more town than city atmosphere, and should be quieter than central London. It's about 30 minutes by train from Paddington station. You can take the opportunity to visit Windsor castle.

Take the bus to Windsor from Heathrow Terminal 5, takes about 45 mins - the castle is GREAT, the town is very touristy.

FirstGroup operate a bus service from the Central Bus Station at LHR to Windsor, with the trip taking about 30 minutes.

Is your layover at Heathrow or Gatwick? I assume it's one or the other since you mention a flight to the US which I think rules out London City airport and Stansted.

Neither Heathrow nor Gatwick is in London, and as has been pointed out already, you will not have 8 hours in London. Whether we're talking about Heathrow or Gatwick, you will have three or at most four hours in London. That would be enough for a quick look around.

I think RJean's answer assumes you're connecting through Heathrow.

If you're a fan of English breakfast, I recommend Regency Cafe -- a full set breakfast for £6! It opens at 7 am Monday-Saturday and is closed on Sundays.

I'd then just wander around central London (staying close to Tube stations, but the network is dense in central London) for an hour or two depending on how much time you have, and then head back to the airport.

For these kinds of layovers, which I've done in Paris and Amsterdam, I personally prioritize food because I like to eat, I think it's a nice change of pace from the food in airports and on planes, and it's an easy way to get both a local experience and take care of a basic human need. But your opinion may differ!

I see now that his final destination is the US. Does their first flight originate inside the UK or outside? If outside do they want to add the time to go through passport control etc? If so, I can make the case that their time to do anything in the area or London is basically 9 to 12 at best. Might be better off finding a lounge, paying the fee and just hanging out.

I had an eight hour layover at Gatwick last year. Rather than try to get into London and back, I did what Ed suggested above....paid to get into a lounge. It includes food and drinks, wifi and a relaxing place.

If your first flight lands (hopefully) at 6:15 and you have 8 hours including check-in and security for your flight to the US, then your flight must be around 6+8=14, or 2pm or so. But you say you have time until 1200ish. That would only give you 2 hours at the airport for the second flight and flights to the US generally require 3 hours. Is the arithmetic wrong or do you know of a way to shorten the check-in time by an hour?

Anyway, with 11 o'clock back at the airport (which one) and an hour likely transit time (which airport) you need to leave Central London at 10. Landing at 615, out the doors before 8 (which airport) gets you into London around 9.

So one hour to eat breakfast.

All,

Thank you so much for the responses, here's a little more info on the trip. I'm coming from another country to Heathrow and then to the US. Also, I wasn't anticipating a 3 hours prior requirement for departure as I've found that in most places 2 hours prior sufficed. However, if that is how long it'll take to get back through customs and security then I'll have to adjust my timeline if I leave the airport to go explore a bit.

Also, some additional information about myself...

While I like to go see some of the tourist attractions in a location (Edinburgh Castle, Eiffel Tower, etc.) I tend to prefer avoiding a lot of the touristy areas in favor of actually seeing more local areas and eating where the locals eat. It tends to be somewhat cheaper, the food is often better, and you actually get to experience and see the culture a bit more in my opinion.

I guess at this point my question is, is it worth the time and effort based on my itinerary to depart the airport to go see whatever corner of London I can based on time available during this relatively long layover or should I just go pay to sit in a lounge at Heathrow? If the latter, what is the average cost for that?

I would never show up at a major airport less than 3 hours before a transatlantic flight, because I don't relish paying thousands of dollars for a last-minute one-way ticket to get home. I wouldn't go into London for such a short time. If I were not brain-dead upon arrival (which I always am, but you may be luckier), I'd go to Windsor.

More info on a Heathrow layover:

Standard advice from UK airports is arrive at airport 2 hours before flight for domestic/European flights and 3 hours for international flights.

I'm going to be the contrarian and say I have never shown up for a transatlantic flight three hours ahead of time. Closer to two. I check in online, print my boarding pass at home/hotel and go straight to security. Some airlines require a passport check before security but that is a separate line from check in. (Even the one time I checked a bag it was two hours.)

With all that I have always had plenty of time to sit and have a cup of tea before boarding.

So Frank II is that your advice to our poster here?

I think only you can answer that question. If it were me, it would depend.

If I were coming off a long flight and tired, I’d probably just stay in the airport.

If I were coming off a short flight, I’d take my chances and try to head into London, knowing that I would just have a couple hours. I always spend my last morning in London having a nice breakfast and taking a walk through one of the neighborhoods before I head to the airport. What is it that you’d like to use your time for? Do you want to see something or just go for a walk or get a good meal?

A few considerations:
1) Will your flight arrive early or late? (you won’t know until you arrive)
2) Will you encounter a long queue at immigration?

3) Plan on an hour on the tube to London each way
4) If I have checked in online, then I don’t generally do the full 3 hour in advance since I know that I will be able to skip the check-in queue. I typically aim to get there 2.5 hours in advance which has always left me plenty of time to have lunch in the airport.

I don't know how much luggage you'll have or if that's checked through but on a nice July day I'd fancy being outside. A few stops along from Heathrow on the Piccadilly line is Osterley, putting youwith within a short stroll of Osterley Park which is Georgian National Trust property. You won't have much time to visit the property itself as it's opening times don't work for you but the Parkland is open from 7.30am (and free) and brunch is served from the Stables restaurant from 10.00am.

I fly through Heathrow and out of Heathrow several times a year and, generally speaking, 3 hours is the minimum check in time for this airport to get on an international flight. Sometimes it is barely enough time and sometimes I'm left with a spare hour+ to enjoy the amenities of the airport. There are some airports where 2 hours is plenty of time...unfortunately Heathrow is NOT one of them.
