Expiry: Mar 31, 2016
From now through March 31, 2016, buy Alaska Mileage Plan miles and earn a bonus of up to 40% more miles. The rules are as follows:
Therefore, you can buy 84000 (=60000+24000) miles with $1773.75 USD (if you live in US), which is not a bad deal.
Note: Miles are purchased from Points.com for a cost of $27.50 per 1,000 miles, plus a 7.5% Federal Excise Tax, and GST/HST for Canadian residents. Miles are non-refundable and do not count toward MVP and MVP/Gold status.
From my point of view, Alaska miles is one of the best miles program for now. I like it very much. If you are interested in it, you should also apply a MBNA Alaska World Elite MasterCard through GCR (annual fee $75 with 25000 welcome miles).
