一、亚航假日酒店+机票必须是往返，不能选单程吗？

只能在你的邮箱里面查收，没有其他途径。订单的正文里面有链接，通过链接可以把订单保存为pdf。所以，在你保存为pdf之前，邮件一定不能弄丢了。

二、亚航假日能看到亚航的促销信息吗？

亚航假日主要是做“机+酒”，就是机票和酒店一起的优惠，如果你想一起订机票酒店，亚航假日就有不少优惠。

三、我需要给海外酒店写一封邮件，可以帮我翻译下么？

hello, I reserved your hotel at Air Asia online.

I 'll check into your hotel on May 4th, 2018, and check out on May 10th, 2018.

Because the flight will take off at 6:00 p.m on May 10th, 2018, I must check out by 2:00 p.m on May 10th, 2018. So can you deal with such a case?

If you can't, please tell me how to do next?

please confirm again, thank you very much!
