On Dec. 15, the Membership Rewards program in Canada will change the conversion rate for converting points into Delta SkyMiles and Continental OnePass miles. Points currently transfer to miles on a one-to-one basis, but as of Dec. 15, one point will convert to three-quarters of a mile in both programs — a loss of 250 miles for every 1,000 points converted.

With a 25 percent loss in value on the horizon, members should seriously consider hastening any planned conversions. A minimum of 10,000 points can be converted and there is a fee of 3,500 points to do so. To convert your Membership Rewards points to Delta or Continental miles, call (800) 668-2639.

This represents yet another diminishment to the benefits Canadian Member-ship Rewards members receive. In fact, many of us still haven’t completely recovered from the abrupt end to the Membership Rewards/Canadian Airlines relationship, which occurred two years ago.
