我尝试在ANA上查询中美往返的税费，然后网站说：
Your specified itinerary cannot be processed online
有朋友遇到过这种情况吗？这种情况一般为什么发生呀？有没有别的渠道可以去查查换票的税费呢？
收到了ana的邮件，原来跨过三个zone的票不能网上出，详情见下面
According to our new rules, award itineraries that cross more than three zones cannot be booked on ANA website (New York -Zone 6- to Japan -Zone 1- to Shanghai -Zone 3).
