"My Travel Rewards and my wife's alumni card haven't seen a single swipe in at least a decade. Those, along with the BankAmericard the analyst talked me into opening last year which has never had a single swipe." 
That's what I've seen happen with BOA pulling from other lines. Hence why I'll only have the one Merrill Lynch card which is plenty.
Since a CSR told me that on the Merrill Lynch card's he has personally seen people get and have $300,000 credit card lines on the ML card.
The ML card is not only one of the most badass manly man looking cards it's like an AMEX Black Card-lite. 
I just got a credit score letter from BOA/Merrill Lynch in the mail today from when I asked for my CLI on the 25th.
My Transunion FICO score was at 775.
But look at how much credit scoring hate they're throwing at me (five things) and that's with a 775 score.
I feel like this when they say these things about my credit file.
