Recently, on a very long last flight of several, after having been awake for (yes) 48 hours (lots of it in pain due to a fall), I finally fell asleep on the plane. First time ever in my life I was able to do that.
Had told my husband I brought my water with me (don't drink anything they give me usually) in case of thirst. He knew I'd had a terrible 48 hours, and never could sleep on the plane. The FA does not awaken me; but HE leans over (amost always in across aisle seats) and shakes me awake to see if I want a Coke or whatever. Never got back to sleep. He, of course, did. As always.

If I EVER go anywhere with him again, seeing as how I make the arrangements, he will be in row 33+, in a middle seat. Preferable the last one, that doesn't recline. With a baby with an ear infection, someone very large, and/or smelly. I will spend whatever it takes to not be in the same cabin.
