Disappointing data point I thought I'd share: I did a product switch from my Tim's DoubleDouble Visa to an AeroPlatinum Visa. I was not eligible for the 5,000 point welcome bonus because I'd already held the Visa Aerogold Infinite card (2 years ago). I asked why because I'd never held the Platinum Visa before. I was told it was because it's in the same 'card family' (Aeroplan points). I was given 2,500 Aeroplan points as a retention bonus (they offered - I accepted...I have no other card I'm interested in switching to, except more no-fee cards)....

Has anyone had success product switching and receiving the associated welcome bonus after leaving more time in-between card switches within the same 'card family'?
