一般针对长途洲际航班（具体要看机票的fare class）。 一般中美之间单程升舱是40 点或80 点。 单程洲际航班可以用40个PlusPoints从经济舱（economy） 升级到商务舱 单程洲际航班可以用80个PlusPoints从折扣经济舱（discounted economy）升级到商务舱 United Fare Class 如下，请注意 economy 和 discounted economy 在升舱时点数差别很大。 A – First class B – Economy – Full fare (even though Y-class is the highest level in coach, it’s still considered a full fare) C – Business class D – Business class E – Economy F – First class – Full fare (“FN” is for MileagePlus Standard Awards) G – Economy – Discounted H – Economy (“HN” is for MileagePlus Standard Awards) I – First (2-cabin)/Business (3-cabin) – MileagePlus Saver Award class (“IN” is expanded award availability for GS/1K/Plat elites) J – Business class – Full fare (“JN” is expanded MileagePlus Standard Award for elites and Chase credit card holders, as well as an upgrade class from Y-fares for elites) K – Economy – Discounted L – Economy – Discounted M – Economy N – Economy – Discounted O – First Class (3-cabin) – MileagePlus Saver Award (“ON” is upgrade class on 3-cabin aircraft) P – First/Business class – Discounted (“PN” is upgrade from B/M-fares for elites; only GS/1K can upgrade from M) Q – Economy R – First (2-cabin)/Business (3-cabin) – Upgrade bucket (“RN” is expanded availability for elites) S – Economy – Discounted T – Economy – Discounted U – Economy V – Economy W – Economy X – Economy – MileagePlus Saver Award (“XN” is expanded availability for elites) Y – Economy – Full fare (“YN” is an expanded MileagePlus Standard Award for elites and Chase credit card holders) Z – Business class – Discounted (“ZN” is for MileagePlus Standard Awards) 在可以直接升舱的情况下，可以接受先升舱再付款。 在使用Pluspoints的时候，由于美联航升舱位置有限，大多数情况下UA系统可能无法立即确认升舱，而是进入waitlist，一直等到登机前才升舱成功，这种情况下需要在升舱座位确定前先付款。如果升舱失败，退款。如果升舱成功，点数会被扣掉，所以升舱成功后恕不退款。 感兴趣请站短联系。
