Maybe I'm missing something blindingly obvious though? I can't help but think banks and card providers aren't going in to debt to provide these rewards. The price is baked in to costs to cover the extra fees banks charge when rewards card holders use their card.
better yet, get a card that gives you 3% when you buy gas or 5% back when you buy stuff at a store you shop at anyway (Target does this, for example).
if you're clever, cash can be amazingly flexible. its easy to redeem and accepted in most places.
- Regular 1% card: $9000 at 1% = $90
- Amex Blue Cash: $5525 at 0.5%, $975 at 1.25% (for the first $6500), then $2125 at 1.5%, $375 at 5% = $90.44 (the splits assume the average spending habits of 15% on "everyday purchases")
is there an annual fee?
They do have a calculator to help you figure it out.

I would also suspect (haven't researched it) that reward paying cards will have a higher interest rate than non-reward cards.
My standard merchant fee rate might be 2.4%, but if you use a 'airline miles reward card' with me, I may end up having to pay 2.9% or 3.4% (or more). I can't not take your card - against Visa/MC terms of service - so I'm stuck paying for your 'rewards'.
On the personal side, rewardsnetwork lets me earn up to 5 miles per dollar at participating restaurants. Since my fiancee and I don't cook we earn quite a few miles this way too.
3% merchant fees on that $40k is $1200. The cost of a couple flights is probably a few hundred to $1000 or so. Even at regular merchant rates they may still turn a profit, cause most people won't redeem points. But they'll charge a merchant higher fees for the rewards card anyway.
You're already spending $40k - understood. Most people aren't, and are enticed in to spending more than they should to get 'free' stuff. Insane.
You can however charge your federal income tax (and some state income tax) payments against your card for a fee.
American Express even lets you use rewards points to offset this fee.
I think most schools are charging fees now, though. There used to be a scam where you could massively overpay you tuition bill on a credit card and then the school would cut you a check for the difference. (Lots of people legitimately end up overpaying because grants or loan dispersements can hit your account at weird times)
