1) Citi Premier
- I see most people here laugh at TY points but I find this to be my most valuable card overall and gets most of my spend
- As a Citigold no annual fees on any of my Citi cards
- Effectively get at least 2.66 TYP per dollar spent (flight points + purchase points + 33% conversion premium when reedemed for airfare). Plus small annual bonus and occasional other bonuses
- I only redeem TYP for airfare. Full flexibility, and you get miles and EQMs for the flights (I would generally not sit on a plane without EQMs), which often offsets a good portion of the TYP used anyhow

** Is my logic above flawed? Why don't more people use Citi Premier? **

2) SPG Amex

Get wife to run business expenses through various cards as necessary, although I have not really taken advantage of sign up bonuses in 2011 (simplicity of the same cards for business vs. always tracking new stuff)

3) Delta Platinum Amex - helps with my DL Diamond status

4) Chase BA Visa

5) Citi AA MC
