The American Express Platinum (Canada) has just increased the sign-up bonus to 75,000 Membership Rewards points after spending $1,000 in the first three months of ownership. This is an amazing deal! We have never seen such a high sign-up offer on any card in Canada, ever.
The 75,000 Membership Rewards points can be converted 1:1 into Aeroplan and BA Avios (often with a 25% bonus to Avios).
Now, this card has a hefty annual fee of $699, however, in your first year, you will get two $200 travel credits (once per calendar year). This makes the effective first year fee $299. You also get complimentary lounge access, PLUS A GUEST, in any Premium Plaza lounge or Centurion lounge. Further, you get a complimentary Priority Pass, which lets you use hundreds of lounge around the world for free (will actually be using it to get into the lounge in Ponta Delgada this weekend). You also get SPG Gold status, and a number of other benefits. Finally, you get the best travel insurance offered on any card in Canada.
Considering this is such an amazing deal, I would get on it right now. You never know when the deal will be pulled (indeed, American Express has been devaluing a lot lately).
You can only get this deal if you use a referral, and I always appreciate the support of readers when they use my referral link.
