Use to consult there. What a mess. That said, 3x speed of crap is still crap. Ben's probably just checking email and uploading his blog, not much of a bandwidth hog.
I forget the exact #s, but I believe their "slower" speeds were 1.5M...shared among the WHOLE plane. What was particularly disturbing is the pilots would all get together on a unlimited plan, and share it in their pool of 10-15 pilots for each pool. Soo, even if you see all of F asleep, you can be assured the pilots are sucking up what is available.
Typically the biggest planes are the ones w/ the faster speeds. Well, there are 2-3 times the # of pax on them too, that's how they justify putting in the Sat. communications (which is pretty expensive for them) b/c on the bigger planes, they know the %age uptake and what the, rough, usage will be.
Finally, it isn't the F cabin that sucks the bandwidth most of the time. it's the pilots streaming video or coach w/ the family of 4 with 2 kids streaming some game. F is usually trying to do work, which generally equates to lower overall usage of bandwidth.
