I always grab an isle seat so when I am getting settled in on an ultra long haul like Mel>Lax I'll always greet my window seatmate with a little chat like: "This is a really long flight. If you need to get up don't worry. Just ask and I'll get out of your way. If you need to wake me up, that's okay. I will not annoy you with any more chat. Have a good flight." Does anyone else do anything like this? p.s. I'm normally in Y+ or J.
