Let us look at a few and you can decide for yourself. Let us assume the trip is to take place a week from now [September 6th at 12:00 PM], and we're going from LAX [Los Angelis] to London Heathrow(Great Britains largest airport). We'll try for one adult round-trip ticket as well.
(Note: I'll be giving these results a subjective score based on service and features)
Expedia.com:
Expedia has a quick, compact interface. One click to set your trip coverage (Hotels and cars are even included in the price as an option).
Expedia gave me a price-tag of $845. Not quite on the cheap, the trick to Expedia is using their explore by destination interface on the upper-right. there you can find deals for hotels and flights (Maybe).
A real great feature of Expedia is marked "Today's Deals" There you can find quick in-country hotels and flights for under a hundred bucks.
Break down out of ten:
Ease of use: 10
Scenario Price: 4
Flexibility: 7.5
Difference in price: +106
Over all: 19.56
Hotwire.com:
Hotwire directly confronts the issue at hand. "Discount Airfare!" which is exactly what we want, especially considering the trip at hand.
I got a better deal here, though you can't expect a great drop in price with the general distance of my test trip (What can I say, I like working with big numbers). Just for using Hotwire to book I only have to pay $713! More than a one-hundred-dollar Saving.
Right after i clicked the submit button the fair price changed to $739. Still a hundred-dollar save, but I'm hoping this is a rare find and not something concurrent.
Ease of use: 10
Scenario Price: 6
Flexibility: 7.5

Priceline.com:
Time for the standing holder of bragging rights. According to their commercials you can save up to half off of the competitors prices!? Let us check that, shall we?
$849 I certainly didn't expect that. The site itself seems to work about as well as Expedia. The name your own price feature seems to put you on a wait list. I wouldn't click any further as it asks for some registration information.
Ease of use: 10
Scenario Price: 3.8
Flexibility: 7.5
Difference in price: +110
Over all: 20.2
In the end, it's the specific trip you want that counts. I'm sure you can find something wonderful to do for a small price. I think it's best to plan your own walking tours using something like google maps.
(Well... That might be more of an urban hike then a walk, but you get the idea)
