出港航班旅客用英语怎么说

出港航班旅客用英语通常称为"outbound flight passengers"。
"Outbound"是英文当中"出发"的意思，来源于"out"和"bound"的结合。"Out"有"向外"的意思，而"bound"有"绑定、限制"的意思，因此"outbound"可以理解为"向外出发的"。
下面是一些使用"outbound flight passengers"的英文例句，以及它们的中文翻译：
Please make sure that all outbound flight passengers have their boarding passes and passports ready for inspection.
请确保所有出港航班旅客准备好登机牌和护照以便检查。
