Yes, the take rate has increased from 4% to 7% in the past year. That's great news year over year. But it is still a pretty low number IMO. Even more interesting to me is that the folks who generated the report suggest that, at 7% uptake, in-flight internet service is somehow a competitive requirement rather than just a nice feature. So ignoring the fact that most flights in the USA still do not offer the service it is apparently a requirement. More on this report here and here.
