Did you try Captain Cheapo's solution instead?

I think the ground is used. I have heard that using the grounded wire can help reduce static electricity on the aluminum casing of a MacBook Pro, and if you'll notice, the round metal knob thing that the cord attachment slides into on the brick contacts a metal part in the three pronged connector attachment that doesn't exist in the two pronged connector attachment.

With that being said, I'm not so sure if the ground will do much on an airplane. :-)

sure does. the earth ground keeps the body of the laptop from buzzing. boombox cords will not help this. it should also be the case on the plane, since the ground is probably wired to the plane chassis.
