Fly Air Canada return to London, England between October 16 and December 10, 1999 in Executive First or full fare Hospitality Service, and you could earn enough Aeroplan miles for a free reward ticket on Air Canada within North America.

Applies to eligible Air Canada direct transatlantic return flights purchased and flown in the same booking class in either Executive First (J fare) or full fare Hospitality Service (Y fare), between October 16 and December 10, 1999. Mileage earned on upgrades from Y fare to Executive First (C fare) applies as per Y fare offer . Return flights in J earn enough miles (total = base + all bonus miles) earn 25K miles. Return flights in Y/C (total = base + all bonus miles) earn 15K miles.

This is not that great--you would get 8K miles in Y anyway (or for a discount ticket). That means you are only getting double miles for a Y ticket (about 7K miles). The J is a bit better as you earn 15K extra miles (25K compared to normal 10K) but does not apply to upgraded tickets. I presume we will get miles on top of miles for the fall bonus promo (i.e a J class one-way ticket will net 4K base plus 1K class bonus plus 1K fall promo bonus plus 7.5K special bonus = 13.5K each way), but then again, maybe they have this all factored in to their 25K.
