Who can use my companion fare code?

The Mileage Plan™ member who owns the companion fare 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 code, then the member''s name must match the name on the credit card used to purchase the reservation.

看起来要用你的信用卡，可以的吗？或者必须转给和你同名的人？

也许实际执行起来和FAQ或许不同也不一定。lz你有实测过吗？
