促销时间：截止至 2019-5-21
官网简介：
Get 50% bonus Avios when you buy or gift Avios before 21 May 2019. Buy up to 200,000 Avios during the offer period to get up to 100,000 bonus Avios.
成本分析：
每个账号每年最多只能购买 20 万里，加上 50% 奖励就是 30 万里。
您可以获得的里程：200,000 + 奖励 100,000 = 300,000 里，
价格： €3,601 欧元，
成本：€3,601 欧元 ÷ 300,000 里 × 10,000 = €120 欧元/万里 ≈ ￥900 元/万里。
注意：
购买里程后通常会马上到账，但是如有例外情况，需要等待 5 个工作日才能到账。
需要注意的是，购买里程的价格会自动转换成您注册账号时填写的所在地的货币或者美元，但是其他货币的价格可能会比欧元的价格贵很多。所以购买里程时，不妨尝试把注册地址改为法国，使用欧元价格购买，之后再改回来。
另外，新账号是不能购买里程的，您的账号上需要存在至少 1 里程才能购买。这个问题不难解决，只要您手上有酒店积分（万豪、IHG、希尔顿等），先转一点分过来就行了。
众所周知，BA 里程是短途利器。在国内，兑换国泰、港龙或者日航的机票都非常合适；在国外，兑换欧洲、澳洲或美国，境内短途都非常划算。
