US Airways is offering a bonus of up to 100% when you buy its miles.
You receive a 25% bonus for buying up to 9000 miles, 50% for buying 10000 to 19000 miles, 75% for buying 20000 to 29000 miles and 100% for buying 30000 to 50000 miles.
Assuming you get the 100% bonus by buying the maximum 50,000, you will be paying $1,881 including tax for 100,000 miles, so (converting to £) 1.16p each.
The key thing to remember is that US Airways has now merged with American Airlines. At some point during 2015, you will be able to convert your US Airways miles into AA miles. You may therefore see this promotion as a cheap way of topping up your American Airlines miles, assuming you don’t need them immediately. You will run the risk of an American Airlines devaluation coming along at some point.
US Airways joined the oneworld alliance in March so you can also now redeem these miles directly for British Airways and other oneworld flights. It is not hugely flexible, though, with no one-way redemptions allowed and fees for ‘short notice’ ticketing. I would only get involved in this offer if you are already familiar with the US Airways programme and know how to make the most of it.
The offer runs until September 30th. Your US Airways account must have been open for 12 days before you can take part.
PS. Don’t forget that Hyatt Gold Passport is still offering a 30% bonus when you buy points before September 15th – click here and scroll down to the Hyatt logo
