Air Canada recently announced the 2012 Top Tier program for those who have or will qualify for it. The following is taken from the Air Canada site:
Enhanced Select Privilege: 2012 Top Tier Bonus
New this year, Top Tier members who choose the Top Tier Bonus as one of their Select Privileges will enjoy a 25% Aeroplan Mile Bonus on eligible flights operated by TAM. This complements the current range of airlines participating in the Top Tier Bonus, including Air Canada, Air Canada Express, Austrian Airlines, bmi, Continental Airlines, Lufthansa, SWISS and United. Unlike in previous years, note that this year ANA will no longer participate in the Top Tier Bonus.
Super Elite Threshold Gift
New this year, Air Canada Super Elite members who achieve the 150,000 Air Canada Status Mile threshold before December 31 will be rewarded automatically with 15,000 Bonus Aeroplan Miles. Members achieving the 200,000, 250,000, 300,000 or 350,000 Air Canada Status Mile threshold will continue to be able to choose from a range of exclusive gifts, including Bonus Aeroplan Miles, gift certificates and electronics.
Expanded upgrade eligibility for Prestige members
Air Canada Prestige members will now enjoy access to upgrades from all Tango Plus fares on flights within North America, including Sun destinations. This change will be effective for upgrade requests made as of January 1, 2012.
