Looks like Air Canada has been tinkering again, and this time, the occasional traveler will not be happy.
On the heels of US Airways cutting their mileage expiration time from 3 years to 18 months, Air Canada has gone much deeper than that. Upgrade: Travel Better points out that not only will you now have to earn miles once every twelve months to keep them active, they now have an ultimate expiration date of 7 years from the date of accrual. This starts January 1, 2007 with all previous mileage being given an accrual date of December 31, 2006.
For frequent travelers, this is a non-event, but Air Canada has made some more positive changes for that group. The airline has been big on selling passes for travel during a certain time, and now they have an all-North America pass. Basically, plunk down a flat fee and you can fly as much as you want in the area you purchase during that time. It’s a pretty cool idea for the frequent flier, but this doesn’t work for the lonely casual traveler.
