Frank,
I`m not following your reasoning here?? Could you help me out? Why are they revenue negative? Detractors from whose bottom line; Airlines, Wencor, Edig?
We are bombarded daily about this IFE and that IFE but have not heard of airlines jumping aboard unless they are embedded in the aircraft at the time of it manufacture. (And those are NOT revenue generators, but in fact, detract from the bottom line)
Thanks.
