You can exploit airline alliances to get some great deal (i.e. transfer points to Singapore Air to redeem on United domestic round-trip first class= only 40k miles).
The promotion when I signed up was 50k miles to start and no annual fee for the first year,
thereafter $175.
This alone makes it very hard to make your money back. If you charge $4,000 a month this basically means you won't accrue any points beyond your annual fee until like the 5th or 6th month of each year.
Also, if you fly a little bit every year but not a ton, the Chase/United card is a pretty good deal. $50 annual fee but you get Premiere Status to begin with (get on plane sooner, your bags are first at the baggage claim, and you can check 2 bags for free for each passenger in your party when you use the card to purchase airline tickets.
