Adjustment for non-balanced passenger loads? It is well established (How Centre of Gravity (CG) is adjusted? and elsewhere) that adjustments can and need to be made to insure that airplane loading maintains a suitable center-of-gravity for the aircraft fore/aft.  However, these questions and answers appear to deal only with fore/aft adjustments.  Does a plane such as the MD-88 which has unequal seating (3 seats on the port (left) side of the aisle and 2 on the starboard (right)) have much of an issue with port/starboard balance, and if so, is there standard way of dealing with more passenger weight on the port side of center-line?  

I would assume this could be handled with unequal fuel tank loading in each wing, or air surface adjustments, but am curious if in practice this is an issue or not.  Or is there anything built into the design of the aircraft to handle this expected unequal passenger loading?
Asymmetrical lateral loads within the fuselage are not far enough away from the longitudinal axis to generate any significant moment arm.  It is an issue, but not one that is planned around or proactively compensated for.  Any imbalance in flight can easily be overcome with a little bit of aileron trim.
