I cancelled my 2 CIBC Aerogold Infinite in Oct 2013
re-applied the new CIBC Aerogold (20K) in Feb 2013, got approved no problem (again stupid high limit)
Now the key is - when do I apply for 2nd CIBC Aerogold card, hee hee.... for another 20K bonus
Hopefully it won't be declined.... so I'll wait a bit to apply
