最好打电话问问expedia.Does the 24-hour refund/reservation requirement apply to tickets purchased or reserved through a travel agent or online travel agency? No, the 24-hour refund/reservation requirement for airlines does not apply to tickets booked through online travel agencies, travel agents, or other third-party agents. However, these agents are free to apply the same or similar procedures to provide equivalent or similar customer service.
我的理解也是这样,谢谢妹子
或许是订票24小时之内取消免费 否则要收费
在美国的网站上订票,24小时之内免费退票
