请教~~美国西南航空问题~~~万分谢谢

一个月前定里西南航空的机票，之前确认邮件都收到，今天又收到它的邮件Your trip is around the corner!，这个应该是广告邮件吧？不会出现航班取消或变更问题吧？~~~Los Angeles awaits!Are you all set for your Los Angeles trip? Not to worry! We put together some special deals below to help you finalize your plans. Happy travels and thanks for choosing Southwest.

一共定了3趟航班，就这趟航班收到这样的邮件，而且还有我的订单信息，有点奇怪感觉~~~
