I will go to just about any length to avoid LHR. The only exception being when I am actually terminating in London and not transiting. It is really the most intentionally wretched airport I have ever visited, although they're all miserable in their own special ways.
I do. It's not so benign as to be out of boredom, but out of the perverse English character. I'm sure Heathrow is some Enochian pun related to jumping between hell, purgatory, and limbo.
(Yeah, yeah, don't put on your clever pants, I know where limbo is!)
