Question

Answer 1

are you going to be allowed to leave the airport? (i'd check re visas etc, a lot of stopovers aren't allowed off on a jolly around the country)

if you've got 6 hours, you'll need to get the train or bus into london at extra cost, which'll kill about an hour either way, which leaves you 4 at most (i'm guessing moving around the airport will take some time)

you're not really going to get much done in that time... you could get a meal, or visit one or two london icons or galleries, but do you want to be in a rush?
