Hi!
Wegen Inseat: Guck doch mal bei seatguru, was da über Deinen Flieger steht. Da steht z.B. bei einer Boeing 777-200:
"In Economy, each seat features an individual entertainment system however underseat space at all A, J, D, and F seats is limited due to an equipment box beneath the seat. Not all of American's 777's have the same seats in Economy with power ports. Some aircraft only have power at seats 30 C and G."
