Flying on an United A320 (I think it's the same set up as the 319) with wife and kid, and an infant on a lap, so four of us in one row. Row 7 bulkhead looks good because it has the cutout and plenty of room for the kids to play on the floor.

But I'm wondering if the fixed arm rests would be a bummer, since we wouldn't be able to put them up and sit all four in a row.

Any kid friendly suggestions? Row 7 or Row 8?
