walk to the airplane will be choreographed.  Obama will emerge from one side of the bullet-proof, tinted-window black SUV.  He'll go over to the other side, open the door and out will come Clinton herself.  He'll probably extend her his hand, as the distance from the seat to the ground is probably pretty high for someone 5'6.  

Then Clinton will point out the bag that she is bringing with her and Obama will make sure that the cameras catch him carrying it for her.  Reggie Love and Huma will be trailing in the background.

It should be hilarious.
