英国航空公司（British Airways）推出购买里程促销活动，通过英航官网购买 Avios 里程，可获额外 50% 奖励。50% 奖励已经是英航里程促销的最低价了，而且不会经常出现，所以有需要的别错过此次机会了。
促销时间：即日起 至 2018年5月8日
If your Avios balance doesn't quite stretch to the reward flight or cabin upgrade you've got your eye on, then purchasing Avios will give your balance a boost to help you get away sooner.
You can also purchase Avios as a gift for another Executive Club Member – make sure you know the recipient's full name, email address and Executive Club membership number. Purchasing Avios as a gift for another Member does not come out of your personal allowance so you are still free to purchase Avios for yourself.
Purchase or gift up to 100,000 Avios now.
在以前，每个账号每年最多只能购买 10 万里程，这次促销一个账号可以购买最多 20 万里程。
您可以获得的里程：200,000 + 奖励 100,000 = 300,000 里程，
价格： €3,601 欧元，
成本：€3,601 欧元 ÷ 300,000 里程 × 1000 = €12 欧元/千里 ≈ ￥92.3 人民币/千里。
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。
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（SPG、IHG、希尔顿等），先转一点分过来就行了。
