This will be very heart braking news for you
Good news as Canadian you can earn kris flyer points through HSBC MasterCard but bad news is it will take you twice as long
The other bad news is that Lufthansa Miles and more and Kris Flyer club membership will charge you a fuel surcharge on each award ticket so first class is going to be over one thousand dollars
The other bad news is if you go with Aeroplan or united you will never find first class because of the situation where there are too many people that want those seats,
So best frequent flyer for what you get is Aeroplan but don't expect first class
Business is available on Turkish which is good
And believe me you are not missing much flying Singapore airline normal first class, in fact it sucks and Lufthansa well that too
Oh by the way a380 is not available for saver redemption on Aeroplan
Unless you are a spending over a hundred thousand dollars a year I would ask you to go with HSBC
Best program is actually SPG Starwood hotel program Because you can change or transfer your points to any airline in the world
