美国联合航空公司周一招来骂声一片：由于机票超量预订，且没有乘客自愿推迟行程给4名美联航员工“让

    座”，美联航决定以抽签形式决定必须下飞机的乘客。一名亚裔乘客不愿配合，机组人员找来机场保安将这名乘客强行拖下飞机，致使乘客受伤。请看本报昨日的报道：

    United Airlines found itself in the middle of a social media storm Monday, after the U.S. carrier forcibly removed a passenger from a flight due to overbooking.

    报道中的overbooking就是“超额订出、超售”，例如：

    It’s a common practice for airlines to overbook, as passengers don’t often take their flight as scheduled.

    超额预定是航空公司普遍的做法，因乘客并不一定按计划乘坐航班。
