I just dusted off an old At&t Universal Business Rewards card I had buried in a desk drawer. Never thought this card would hold any value to me. It was originally a aadvantage business card but I switched it over to avoid the annual fee. Small line (only $1500) and still not close to my go to card (1 TY point= 1 ba mile per dollar spent) as I still carry Starwood, sapphire, freedom, as well as a CO/United, BA card( 1.25 miles per dollar) and Aadvantage.
Still even though it remains my last card to use, I know If there ever is a need to max all cards out, the points are at least of good value now
