本来打算春假带宝宝到加州旅游，机票定好了，是通过cheapticket订的往返票，但是
现在因为一些原因不能去了，想取消机票，研究了半天也没有弄明白，不知道有没有人
了解取消机票我要损失多少钱。
This ticket is non-refundable. Changes to this ticket will incur an airline
change fee of $150 per ticket and an CheapTickets exchange fee of $50 per
ticket.
本来想着订票的钱全部没有了，但是又看到有说
Your recent purchase qualifies you for a courtesy cancel.
Please read the important notes below:
You can cancel your tickets and start over without incurring an airline
penalty.
Your CheapTickets service fee is non-refunda
