AS的companion pass可以让别人用，不必我自己飞，只需用我的信用卡付钱就行。
companion可以累计里程。
加自带的99+$19左右tax，相当于$228-$238一张票，任何AS飞的航线均可。适合去夏威
夷，阿拉斯加以及东西岸间飞行距离较远票价较高的线路。对于一张400+以上的Alaska
Airlines机票，大概能便宜200刀+。 http://www.alaskaair.com/content/mileage-plan/frequently-asked-
Who can use my Companion Fare Discount Code?
The Mileage Plan member who owns the Companion Fare Discount Code must
either be one of the travelers or the purchaser of the reservation. If the
member is allowing two travelers to use his or her Companion Fare Discount
Code, then the member's name must match the name on the credit card used to
purchase the reservation.
Does the companion traveler using the discount earn mileage credit?
Both travelers can earn mileage credit for their flights in their own
Mileage Plan accounts. Please be sure to provide the Mileage Plan
numbers when booking your reservation, or when you check in for your flight.
