7/. One annual trip of 2000 miles by plane (at about 70mpg per

to your job at 45mpgh, or less in congestion..

OK, so for a family of four you have to multiply that up, (which you
don't for an equivalent car journey), and 2000 miles is the round-trip
so you "only" get to go 1000 miles away.

To be more realistic, a single holiday to (say) New York for a family of
four equates to an approx. total round trip of 8000 miles per passenger,
so 32,000 miles at 70mpg. So that's the equivalent fuel use of 16,000
miles in a 35mpg car, which is substantially more than I do in a year.

I wonder how much of what you consume is airfreighted in, though.

If fuel costs go high enough, time to unmothball the 'queen mary' or
whatever..

whats a liner do..40mph? 3000 miles..? 75 hours..thats three and a bit days.

Nice trip.
