很难具体作答, 有美国友人前两天刚买了下周去北京的票, 往返700刀. 他原拟上个月去, 因当时票价高觉得不划算推迟了. 另一友人正犯踌躇, 他找了TRAVEL AGENCY, 单程前往中国内地一大城市要1200刀! 我买过两次美国西北的往返, 一次去他们的OFFICE拿的票, 另一次是网上买票, 自己打印的票. 看看www.nwa.com. Keep an eye on the price, when it's lowest and acceptable, just book it. If your destination is not beijing but other cities, Air China is good, for it allows you to fly the homeland flight with the same luggage policy applicable to int'l flights.
