luggage和baggage的区别在于：baggage一般指装满东西的箱包，luggage指空箱子。如箱包店出售的就不是baggage，而是luggage。baggage与luggage都可以表示行李，但是baggage为美国英语，luggage为英国英语，且两者都为不可数名词。

luggage的例句：Each passenger was allowed two 30-kg pieces of luggage（每位乘客可带两件30公斤的行李）；baggage的例句：The passengers went through immigration control and collected their baggage（旅客通过入境检查后领取了自己的行李）。
