捷蓝航空常常会有里程票折扣兑换的促销，这次的促销是是8折兑换，直接提高了jetblue的点数价值25%（1.4 cent的平均价值提高到1.75 cent）
具体的活动时间和要求如下：
- 4月8日EST 11:59pm前预定，5月2日-6月7日之间飞行；
- 打折日期必须是周二、周三和周六，其余时间没有折扣；
- 5月24-5月30日是Blacout Date，不享受折扣
- 订票时，若满足上述要求，自动显示出折后积分价格
下面看看一个查票的例子：6月5日周一和 6月7日周三的同样的航班纽约JFK飞往古巴哈瓦那HAV，直接买票价格是$151.1，而所需积分分别为7200+$30.6 和 5800+$30.6，因为周一不打折，周三打折，所以积分所需从7200变为7200*0.8=5760实际取百，故需5800 points加上30刀的税费。
这个例子中，没有打折的时候TrueBlue point用到了 (151.1-30.6)/7200 = 1.67 cent, 而折后是 (151.1-30.6)/5800 = 2.08 cent。
TrueBlue积分来源：
- 信用卡开卡。捷蓝航空的联名卡曾经是和美国运通合作的，现在转投了巴克莱银行，推出了3张个人卡和一张商业卡，开放申请的个人卡包括无年费版本的Barclaycard The JetBlue Card和有年费但是福利也更多的Barclaycard The JetBlue Plus Card，前者的开卡奖励10000里程实在是吸引力不大，期待以后提高开卡奖励。后者的开卡奖励为30000里程，虽然也不多，但是有一项类似AA联名卡的每次用点数兑换机票返还10%里程的福利。
- 点数转换。作为AMEX的Membership Reward的Transfer Partner之一，AMEX MR可以250：200的转给捷蓝航空的积分，由于一般估值MR为1.7-1.9美分，这个转换还是相当亏的；Citi TYP可以1000：800转给捷蓝航空的积分（需要持有Citi ThankYou Premier或Prestige或Chairman，否则比例是1000：500），转换比率和MR相同，但是是1000点为单位起转。（4月30日之前转点还有50%的额外奖励，相当于1:1.2）
- 乘坐Jetblue的飞机，以及Jetblue促销活动。
- 徽章活动。捷蓝有一个有趣的Badge系统，有各种任务和等级，有些完成后可以获得额外积分，比如一年飞3次往返获得5000积分。注意需要先加入Badge系统才可以激活。等级越高，可以做的越多。

牧羊场总结：
Jetblue的积分永不过期，且现在TYP有转点bonus 50%，如果你也持有Barclay的联名卡，积分的价值可以提升不少，一张10000积分的机票，打折后需要8000分，持卡10%返还，实际需要7200分，如果用TYP转点，则只需要6000 TYP。考虑到B6积分估值平均1.4 cent，TYP可以用出平均2.3 cent的价值。 在上面的例子中，Trueblue本身积分用到了1.67 cent，故TYP在这个例子中可以用出2.78 cent。
