兌換T&C是這麼寫的,允許,但沒說消耗積分的算法:
Mileage Plan awards may include one of the following: a one-way, round-trip or open jaw itinerary. One enroute stopover at an eligible city may be allowed for each one-way award on eligible international itineraries. An exception allowing an otherwise-illegal open jaw trip is permitted when travel is between the State of Alaska and the lower 48 states and a stopover occurs in Southeast Alaska. When award travel is redeemed solely on Alaska Airlines, one enroute stopover is allowed for each one-way award. One enroute stopover is allowed on a one-way award.
Update: 電聯客服,問了開口程的積分消耗算法,客服說無論你怎麼訂,積分的消耗都是按照航段來分別計算,而不是按照總飛行里程來計算,比如1000+1200miles的中東open jaw就需要15000分,而不是7500分。允許搞開口唯一的好處就是你兩段航班都在同一個預訂裡,還有省下12.5刀的夥伴訂票費。 Award Chart
