Alliant has a 2.5% back card (https://www.alliantcreditunion.org/bank/visa-signature-card)... it does have annual fee though, so unless you spend a lot of money on non-bonused categories it is probably not worth it.
Or if you can stash $100K with BoA or Merrill, BoA Travel Rewards give you 2.625% back (1.5% back + 75% bonus), with no annual fee.
