Recently, I had the pleasure of flying from Vacouver, BC, to Edmonton, Alberta on an airbus 319. I was delighted to find a 110 V AC power outlet in the seat back in front of me. Having never seen this before, I had to take a picture and share it.
Note the power charger icon in the mac window. Also, there is a USB plug visible on the left side of the display. I believe that is for future use on games (the PS3 has a USB input, I think these will allow the controllers to be plugged in and used for game playing).
It’d be wonderful to have power on all flights - kudo’s to the Airbus 319!
