On all the international flights I have been on I have *never* seen a power socket to plug up a laptop. Never. It has always made me wonder if they really exist, I have just assumed that they are for the first class. The flight is on a 747 on Quantis airlines. I have flown on Quantis on a 747 and haven't seen a socket, either. Thus this monster D-cell battery pack :) BTW, has anyone seen an Air socket on a flight before? Because I would really like to know...
