美國東南航空國內線訂位完成是不是在起飛前24小時才能印登機證?
還是直接到櫃台出示護照　和Confirmation Number就可以了
那在飛機起飛前要打電話向航空公司確認嗎？
下面是出現的錯誤
What happened?
The time frame for which you selected to print your Security Document is outside the allocated window. Security Documents may be printed beginning at 6:00 AM one day prior to your flight.

What you need to do:
Please visit us again during that time to print your Security Document or you may check in at the Southwest Airlines departure airport's Ticket Counter, Skycap Podium, and/or self-service RAPID CHECK-IN kiosks (where available) to receive your Boarding Pass prior to proceeding through the Security Checkpoint.
