美國聯合航空公司（United Airlines）推出購買里數促銷活動，通過 MileagePlus 官網購買里數，可獲額外 85% 獎勵。我們知道，美聯航基本上每個月都有里數促銷活動，100% 獎勵或者五折優惠才是最低價，所以這次促銷，剛需可入，非剛需可以再等等。
這裡再說一下，100% 獎勵和五折優惠其實是一樣的促銷。因為美聯航限定每名會員每年最多只能購買 15 萬里數，包含獎勵的部分。
促銷網址：https://buymiles.mileageplus.com/united/united_landing_page/
促銷時間：即日起 至 2018 年 7 月 11 日（約北京時間 7 月 12 日 13:00 左右）
促銷介紹：
For a limited time, get up to 85% more miles when you buy miles. Offer ends July 11.
Buy 5,000 - 14,000 miles | Get 30% bonus
Buy 15,000 - 29,000 miles | Get 60% bonus
Buy 30,000 - 81,000 miles | Get 85% bonus
成本分析：
購買里數從 2,000 里數起賣。
購買 5,000 - 14,000 里數獎勵 30% 。
購買 15,000 - 29,000 里數獎勵 60% 。
購買 30,000 - 81,000 里數獎勵 85% 。
您每年可以最多購買 150,000 里數，要注意的是，這個 15 萬里數的購買限制是包括獎勵的部分，也就是您購買里數後實際到賬的里數。
您可以最多購買：81,000 + 獎勵 68,850 = 149,850 里數，
價格是 $2,835 + 稅 $212 = $3,047 美元，
成本：$3,047 美元 ÷ 149,850 里數 × 1000 = $20.33 美元/千里 ≈ ￥134.5 人民幣/千里。
