Google for Boeing-Connexion. They provede the system. AFAIK only LH
operates it so far, SAS and CX
ordered it, not sure about a roll-out so far yet.
you need your own notebook and you pay approx 10$ for 30mins, and 30$ for a one-flight-flat.
I will probably fly LH
new business on a 744 in December and I will check that out!
