Between now and April 15th, US Airways is offering a deal where you get a 50% bonus when you buy miles (miles normally cost $35 per 1,000 miles, plus some taxes). Then, if you register with points.com, you’ll get another 50% bonus. You can purchase a maximum of 50,000 miles (which will earn you 100,000 miles total) per person.
I’m not one to purchase miles in advance, but lots of people like the idea of getting a business class ticket to Europe for $1870.
If you haven’t yet gotten the US Airways Premier World Mastercard, you should — you’ll get 40,000 miles after your first purchase, with the first year fee waived. Seems like a no brainer in combo with the above offer if you have no miles with US Airways and you’re planning a trip (a co-worker is considering a trip to South Africa this fall, and I will recommend getting the credit card and purchasing the other 30,000 miles she’ll need for an award ticket. She’ll get to South Africa for under $300 — or she could go in business class for about $650). US Airways has generous redemption levels for Africa (70k/110k coach/biz), Australia (80k/110k coach/biz), and North Asia (60k/90k coach/biz).
