關於AirAsiaGo & Expedia一問

差一點成帥哥
今天透過AirAsiaGo訂了酒店,之後已收到確認電郵。而在數小時後,我收到一封來自Expedia的電郵,內容如下﹕

Dear xxx,

Thank you for your reservation request.
May I have your email address, please?
I would like to send you the information of “smart locks” (key PIN code) by e-mail.

署名是該酒店及酒店的電郵。

請問,應回覆嗎?AirAsiaGo是不是隸屬Expedia旗下?(第一次用這網站)
