The view above the Thames from the plane is miraculous. If coming from the east, you will wind along the river in pursuit of Heathrow. Please note, you may not have the window seat. Do try not to be terribly akward when stretching your neck to see Westminster out the window. Furthermore, the view of the Thames from an aircraft and the view of the River from a capsule on the London Eye are not the same. I don't know why I thought they would be. Perhaps I've watched the dragon flight scene from HPDH: Part 2 too many times.
