Presently Ameican Airlines has a few transcontinental flights within the US that is offering wi-fi, Southwest is also testing wi-fi on a few select flights. If you're not on one of those airlines you'll not be able to get wi-fi, although most airlines are looking into wi-fi and hopefully it won't be too long before many airlines will have wi-fi available. If you're in 1st or business class there's a good chance of having a power port in your seat. In economy many airlines are now offering power ports on some of their planes, but many more airlines don't have in-seat power than do. If you know what type of plane you'll be flying on, you can check your airline to see if power ports are available, but you'll have to use your laptop for something other than the internet.

A few select flights on a couple of airlines. AA does some, and Alaska is about to as well.

Some airlines like Virgin Atlantic have ethernet ports built into the arm rests of seats (usually 1st class) to allow web access.
