Hey vthatcher
we've traveled a lot and I decided long ago that the two days after a major time zone shift are all bets off, meaning just feed when he seems hungry. I just could never get my head around the time change and found it easier to just go with the flow until we had adjusted to the new time. Also, on the plane I would BF DS a lot, I mean a LOT. As it was the best way to calm him and help him sleep. I doesn't matter too much to do this over the flight and then go with the flow the next day too, you'll get back on track...(and then fly back again!)
HTH
