Im a Chiflyer too! Thanks for the advice and you Jdiver!
I already have the DC adapter which is becoming more obsolete now the MD 80's regrettably are being put into retirement. I have a strange computer, a Lenovo Helix (tablet laptop hybrid) and im wondering if they do such a thing. Is it an external battery that feeds power via usb on any laptop?
Also one more Q. I dont sleep on flights so am i best of choosing the aisle of this exit? It is wide open right now. I have heard the exit door is a little inhibiting. Im not a tall guy though so not sure i i will be affected
