联合航空在其官网的问答集内，将11/15/2019之后会改为动态兑换
标准的制度，其中＂伙伴航空＂部分的内容，也改为动态标准！先前联合航
空只有宣布自家航班才会有动态的兑换换标准，以下是官方的叙述：
The partner award chart will remain in effect for travel through
November 14, 2019. For travel on or after November 15, 2019, there
may be flights that require a higher number of miles than the
amounts indicated on the award chart. When you search for awards
while booking, you’ll see the applicable award level.
