其实有时我也后悔当时发疯放了几万里到A3，尤其是在这个CO马上涨价的节骨眼前更是。关于A3计划显而易见的利与弊就不多说了，就跟大家分享一个A3兑换比较划算的地方：北美。 在A3的星盟兑换表中 同地区内都是经济25000商务42000。而A3对北美的定义是从阿拉斯加一直到包括加拿大美国（除夏威夷）墨西哥再到加勒比海跟中美地区 相当于跨了四个CO自己定义的分区 相当强悍。并且A3允许来回各一个stopover， 这样算下来兑换条件比同地区兑换CO UA US几乎都要划算的多。但缺点是要收燃油。适合那些当年为了搞金卡的同学来花掉那几万里程，以及常年飞擦航或者ANA等300%累积的F舱的远程航线的人。
再把很早以前的邮件翻了出来 大家都在关心的问题 跟大家分享了
