關於電子票的疑問

以前沒用過電子票。
這次在一個旅行社訂了美聯航的國際航班機票，寄來的機票模樣很奇怪。右邊的boarding pass下面寫著not valid for travel。
請問，這是什麼意思啊，登機前需要換票嗎？很麻煩嗎？

I don』t know who offers ePass and I believe what you have is the eTicket. If so, you still need to check in, select your seats if necessary and get your boarding pass via a ticketless workstation. You can slide one of your credit cards or driver license into the slot of one of the workstations next to the airlines ticket counter and follow the instructions on the tough screen monitor. If you need to check in your baggage, an attendant will be with you momentarily to take care of the baggage after you are done with the check-in.

到機場換boarding pass, 好處是不用排隊check-in

到機場排隊換boarding pass...

同意其他各位講的，絕大部份國際航班還是要排隊換票的。

這回明白了。
多謝各位！

如果是電子票通常你是不用去排的,只要去機場的特殊的電子票KIOSK面前把自己的DRIVERS LICENSE一劃就可以換到登機牌,當然如果你有託運行李的話還是需要排隊的.
