咋觉得像智力题呢?

不知道，帮你顶

嗯，有点象当年的GRE逻辑题，俺也晕了，俺也帮你顶

上次瓜子由同样的问题哦。

俺土人是不懂得。

可不可以问航空公司呢？

If you don't get on the inbound flight,your outbound flight will be cancelled automatically. So in this case, you can only follow agent's advice.

I suggest you also rebook the ticket since the price could be even lower than the price you need to pay to adjust the ticket. And you can call US airway to cancell the ticket and use the remaining value for future use.
