Every CO 777 that I have been on has had ports through row 23. Sometimes they announce that you are supposed to take your battery out of your computer. If they do, and you do, save your work very, very frequently!

If you do not already have an auto adapter, you can frequently purchase combination auto/air adapters on Ebay quite reasonably. I have found the most convenient set up is where the airline plug is between the auto plug and the transformer. I am less likely to misplace the second part with this set up than when the auto plug comes between the air plug and the transformer, because I use the auto plug more often than the air plug.
