Also, 3+1 gives much easier aisle access, which is critical with a kid of potty-trained age, especially on a longer flight.

We're bringing one carseat on board and going to try out one of those RideSafer travel vests for the 4yo (I won it in a contest a few months ago) so we don't have to bring the booster seat.
