You definately want him sucking on departure and arrival, be it breast feeding, a pacifier or bottle!!!
I was never a public breast feeder, but on the plane I would sit against the window, with my husband next to me and a blanket over me and no one could see.
PS: this is a great trick for shots as well, as soon as they gave her shots they would walk out, put a note on the door and we would BF her, and she never cried!
