Sorry, Tim, but the airlines pad their flight times a bit, making objective
comparisons difficult.

BA, VS, and NZ all use B744s on that route, and have published times of
11:00, 11:10, and 11:20.

Compare instead LHR-LAX on VS7 compared with VS23.  The former is a B744,
the latter an A340, and the published time is 25 minutes longer for the
A340. (11:35 vs. 11:10).

To round out the numbers, UA's B777s do the trip in 11:10, and AA's B767
lumbers in just slower than the A340 at 11:40.
