As I know, there are differences between passenger flights and cargo flights. First, passenger flights transport passengers and their luggage to destinations, while cargo flights only transport goods. Second, passenger flights operate with flight attendants on board, whereas cargo flights don’t require attendants as they focus on transporting cargo.据我了解，客运航班和货运航班存在以下区别：一是客运航班将乘客及其行李运送至目的地，货运航班则仅运输货物；二是客运航班执行任务时有机组乘务人员随行，货运航班因以货物运输为核心，无需乘务人员随行 。 Passenger flights and cargo flights have several differences. First, passenger flights carry people, so safety and comfort are more critical. They require cabin crew, passenger seats, oxygen masks for all, and in-flight entertainment systems. Cargo flights carry goods only, so no cabin crew or passenger amenities are needed. Second, cargo flights often operate at night to avoid peak hours, while passenger flights follow daytime schedules more frequently. Third, cargo flights may carry dangerous goods, requiring special handling and documentation. Fourth, security procedures differ – passenger flights focus on hijacking and bomb threats, while cargo flights focus on smuggling and undeclared hazardous materials. Both must follow ICAO and CAAC regulations. 客运航班和货运航班有若干区别。客运航班运载人员，安全和舒适更关键，需要客舱机组、座椅、全员氧气面罩、娱乐系统。货运航班只载货物，无需客舱机组与旅客设施。货运常夜间运行，客运多日间飞行。货运可能载危险品，需特殊处理与文件。安保程序不同：客运关注劫机炸弹威胁，货运关注走私与未申报危险品。两者均需遵守 ICAO 与 CAAC 规章。
