Expedia UK美国租车的问题，求救！！！

5月去美国洛杉矶，在Expedia UK的网站上定了一辆车，费用当场就扣除了。立马收到一封确认邮件，上面写着：2.Please print out both this email and your Trip Details email and ensure that you take these with you on your travels (Without these printouts, your car hire reservation will not be honoured),

但我从头到尾就只收到这一封确认邮件，没有Trip Details email啊！这个是什么？有在此网站上定车并成功提车的大侠来说说。多谢多谢！
