LUX is a much bigger air cargo hub than a passenger airport; that's the difference. There hasn't been long-haul/wide-body passenger service there in many years, but that 4000m runway sees real use. Usually 50% more freight aircraft movements (and many multiples the mass) than passenger aircraft at LUX.
