I think what you're missing is that if that you're that concerned
about saving 70p or even a few pounds, you shouldn't really be flying
out to wherever you're going. How about a week in Hunstanton instead?

I actually flew out for a funeral, but next time I will suggest that it
be moved across the Atlantic to Hunstanton. Thanks for your helpful
reply.

I'm returning to LHR because that's where a flight was available at the
appropriate time. The airline's fare was the same.

I don't think I'm doing the West Brompton thing but I was curious as to
whether there was a better way to do it.
