I don't know how other fly-by-wire aircraft handle crosswinds, but the A320 is really slick at it. Airbus recommends using the "crab-in" technique right to the point of flaring for touchdown then feeding in rudder to straighten out the crab.
The result is the upwind wing will automatically drop into wind and thus no opposite aileron is required to maintain centerline. Just pull back on the joystick to flare and voila...you're down. It really does work. It does go against what I have been trained to do for crosswinds as has most people here with regards to the opposite rudder/aileron method.
Leave it to Airbus huh..!!
