还有个疑问,我是在sunwing上订的package,只是给我发了邮件确认相关信息,那我出发的时候只带着这张纸和护照就行了吗?
Is it an "invoice" that you received by email?
That invoice is not enough.
On the top right corner of the invoice, there's a link, click on it to get the E-documents you need. It's available 28 days before your trip. So if you booked for 2 months later, wait for them to become available.
