支付网络使用的汇率好像和实时汇率是不一样的，有没有办法查到Amex刷外币时的汇率？
另外，Amex Biz Plat是不是没有FTF？
不显示汇率的, 但能手动对比出来
比如你刷了CAD 50, amex app上的Transaction Detail 里面会记录"Foreign Spend Amount 50 Canadian Dollar"和当时对应扣掉的USD 36.41.
然后手动去看google上汇率 CAD 50 = USD 36.40, 就知道汇损的%, 多对比几次心里就有数了, 感觉amex的汇率和google的汇率基本一致的, 通常汇损不超过千分之一. Business platinum 0 FTF
跟amex客服鸡同鸭讲了一通之后他给我发的链接是这个，暂且不知道准不准
lol it’s definitely not the rate they use, they don’t publish that

amex刷外币pending看到的价格和实际post不一样，而chase一般是一样的。
出了欧美国家，category基本就爆炸了
对，这个其实挺闹心的。运气不好的话，刷的时候觉得挺好，post时候会数目变多。
Amex 的汇率不公布，但似乎是根据 processing date 前汇率计算（MasterCard 类似？），所以汇率不可预期，而 Visa 是按 transaction date 计算所以汇率很确定（但是公布的当日汇率似乎是按前一到两天的市场汇率计算的，所以其实是「延后」汇率）。
参考 flyertalk dp：
Amex has confirmed they use the rates found at Currency Converter | Foreign Exchange Rates | OANDA and it happens daily.
It seems to me that based on this thread, one issue is that Amex uses the processing date rather than the transaction date to set the forex rate. The amount that shows up immediately under Pending Charges would use the rate for the transaction date, as any future rates are unknown at that point. Then, it may be a day or more after the transaction date that it gets processed. On top of that, it appears that they have the discretion of using either of two dates to set the forex rate: either the day they process it, or the prior day. It would not surprise me if they just pick whichever is more advantageous to them - discretion to do so is definitely consistent with the language in the Cardmember Agreement.
Amex N年之前是有网页可以查汇率的，现在没了
只有网页上不关痛痒的话
Unless a particular rate is required by law, we will use conversion rates based on interbank rates we select from customary industry sources on the business day prior to the processing date (called the “American Express Exchange Rate”). This rate may differ from rates that are in effect on the date of your transaction. Fluctuations may be significant.
amex汇率其实偶尔还比Google 汇率强。。。
昨天在日本网站买了个东西，下单扣钱后马上对比了一下， 谷歌汇率149的情况， amex 给算了150.。
至少刷CNY的情况下，Amex是最好的
那个汇率是临时的，入账之后会有变化
前两天在东京刷了¥303000，刚刷完pending的时候显示$2000，今天post显示$2031
算一下汇率，最终post的汇率跟刷卡当天google的汇率基本一致，pending的汇率大概是刷卡前2天的汇率
居然还能这样。。。
