英國航空公司（British Airways）推出購買里數促銷活動，通過英航官網購買 Avios 里數，可獲額外 45% 獎勵。50% 獎勵才是英航里數促銷的最低價，但是極少出現，上一次促銷就是 50% 獎勵，但是是一次閃促。這次促銷 45% 獎勵還是不錯的，剛需可入。
實際上英航購買里數服務是由 Points.com 提供，關於 Points.com 的介紹可以參考這篇文章。
促銷網址：https://www.britishairways.com/travel/purchase-avios/execclub/_gf/en_gb
促銷時間：即日起 至 2018 年 8 月 6 日
促銷介紹：
Get up to 45% bonus Avios when you purchase or gift Avios between 23 July 2018 00:01 hr BST and
6 August 2018 23:59 BST. Plus, purchase limit increased to 200,000 Avios.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.
成本分析：
在以前，每個賬號每年最多只能購買 10 萬里數，這次促銷一個賬號可以購買最多 20 萬里數。
此外，購買 10 萬里數以上才能享有 45% 獎勵。
您可以獲得的里數：200,000 + 獎勵 100,000 = 290,000 里數，
價格： €3,601 歐元，
成本：€3,601 歐元 ÷ 290,000 里數 × 1000 = €12.4 歐元/千里 ≈ ￥98.7 人民幣/千里。
購買里數後通常會馬上到賬，但是如有例外情況，需要等待 5 個工作日才能到賬。
需要注意的是，購買里數的價格會自動轉換成您註冊賬號時填寫的所在地的貨幣或者美元。但是美元的價格會比歐元的價格貴很多，所以購買里數之前記得先把註冊地址改為法國，這樣就能用歐元價格購買了，之後再改回來。
另外，新賬號是不能購買里數的，您的賬號上需要存在至少 1 里數才能購買。這個問題不難解決，只要您手上有酒店積分（SPG、IHG、希爾頓等），先轉一點分過來就行了。
總所周知，BA 里數是短途利器。在國內，兌換國泰、港龍或者日航的機票都非常合適；在國外，兌換歐洲、澳洲或美國，境內短途都非常划算。
