目前,国航订票处说他们有5月1日、5月3日北京飞瑞士的机票 但仓位是Y舱（高价仓位）.您目前定的5月5日的CA933是M舱,如果您需要重新定到5月1日的高价舱机票,需要交仓位的差价费RMB 4500.
请别用翻译器 还有其他答案吗 谢谢啦 比较急

优质解答

Currently, Air China's booking office said they have tickets from Beijing to Switzerland for May First and May Third, but it is for class Y (High priced Class). Your present booked ticket for CA933 on May Fifth is class M, if you need to rebook it to May First's High priced Class ticket, you need to pay a total of RMB 4500 price differences.
