vProbably the most unpleasant kind of call that an ground handling agent has to handle is from a passenger with a complaint against the airline. If possible , the ground handling agent should try to correct the problem, but if there is nothing he can do about it , he must simply listen and try to soothe the passenger. complaints usually cover failures in service over-bookings , lost or damaged baggage, delays, missed connections and so on.

3、一位旅客持有效证件到值班经理柜台，声明当天的北京巴黎经济舱客票丢失，值班经理在电脑中找到了该旅客的定座记录，旅客证件、电话号码等都与该旅客讲的相同，请问，可否接收该没有有效乘机联的旅客办理乘机手续？为什么？
可以接收该旅客办理乘机手续。按民航规定，定期客票丢失，旅客应在航班离站前1小时向承运人提供证明，承运人经过核对，无误后可以补开新的客票，但新客票不得办理退票。
