Alaska has launched a limited time and participation offer for buying their miles. The bonus amounts to 40% as you can only buy 10,000 miles at a time and they’ll throw in 4,000 more miles. You can make up to 5 separate purchases. They are also limiting the offer to the first 2,500 members who purchase miles. This bonus is significant as usually to get the 40% bonus you have to buy 40,000 or more miles when they have these bonus sales.
4,000 Bonus Mileage Plan miles when you purchase 10,000 miles. Full details. Until May 3 or when 2,500 members purchase the package, whichever comes first.
