Starting with the obvious:
-Boeing yokes interconnected and mirror A/P activity, Airbus sidestick movement independent of each other and fixed when A/P engaged
-Boeing thrust levers move with autothrottle engaged, Airbus thrust levers fixed with autothrust active
-Boeing will remain in VNAV PTH even if a selected heading takes aircraft away from LNAV path, on Airbus you need to be in NAV mode to remain in Managed Descent
-Airbus retains ability to engage another vertical/lateral mode after LOC and G/S capture (ie selecting HDG to commence a sidestep), on Boeing must disconnect A/P and F/D first
