Miles and Points is a bit different from money.. When you earn miles and points, one should know to burn em..

Keep enough so that its flexible to book.. but being a mile account millionaire is keeping so many that the points may depreciate in value.. must use em..

As others have mentioned, the first step is to figure out what you want, and then figure out which cards offer the best benefits. Some questions to consider are:

1) Which airlines do you use and how easy is it to get either reward flights or to upgrade with points? Do they charge high redemption fees (like BA's ridiculous fees)?

2) Would free hotel nights be a better value? If so, which brands do you typically stay at for business and for holidays? I tend to focus on Hilton and Marriott because they have a wider range of hotels in the places I travel, and at prices where I'm willing to pay $ as well as redeem miles. Plus, one of my company's preferred chains is Ritz-Carlton (affiliated with Marriott).

3) Will you benefit (at work or for personally) from achieving elite status through the use of credit cards? For example, Continental is my company's preferred carrier and I fly about 10 times per year. I also live near the EWR hub. So it's worth it to me to have the Chase Pres Plus Mastercard. Although it's expensive, I get a Pres Club (now United Club) lounge membership, free bags when I travel and I earn flex elite miles with $ spent. My husband and I also use the Hilton Amex because $20,000 spend gets us Gold status, and that translates into decent upgrade rates, free breakfast, free internet etc.

4) Don't forget the extra point-earning opportunities from using a reliable internet portal. I've found Marriott's to be the best. I make most of my internet purchases by clicking through Marriott's portal. As a result I usually get between 2 and 6 points per $ spent, plus the points I get for using whichever card I use. You might be able to take advantage of this for some of your corporate purchases - e.g., Staples, Dell and other computer retailers etc.

Beware of limits on the number of miles or pointsyou can earn in a year on a card. Typical is 100,000 or 150,000 miles. Some have no limit.

The credit card section of my website below should be of use to you. Spend an hour there and you will know about all of the current offers (I hope).

I do not see the Chase AARP card listed and the OP should consider this one.

+1 on this...Not necessarily miles card but a card OP should consider

If you're looking for a card that gives miles/flexibility:

1. SPG Amex (primary)
2. Chase Ink Bold (for your Visa merchants) -- this card offers an extra 45,000 points for spending over $100,000 per year. The Sapphire Preferred is also a good choice, but given that you're spending $250,000 on a Visa/year, your 7% bonus will only add up to an extra 17,500 points, so I'd go with the Ink Bold.

At these spending levels you will need substantial credit limits, and will likely end up using business cards, rather than personal cards, unless your personal income alone will support them. Business cards require a personal guarantee and are based on your personal creditworthiness, but the issuer will also take into account the company's cash flow.

American Express issues charge cards with no preset spending limit (Green, Gold, Platinum and Centurion), and also credit cards (including the Starwood card) which do have specified limits.

Chase Ink Bold is also a charge card, all other Chase cards are credit cards. Some Chase affinity cards have business versions (e.g. United Airlines), while others do not (e.g. British Airways).

Business cards offer useful features in a business context, each physical card has a separate account number which makes it straightforward to track spending, set individual limits, and replace individual cards if lost.

ime American Express Aeroplat in Canada had no preset spending limit..

When we purchased a 2011 Toyota Sienna AWD Limited the entire amount on the Aeroplat, I quickly found out that there is a credit limit at that point in time that we were allowed to spend.. and was told once put through the initial 20K, and paid the balance down, more credit limit would be granted based on our ability to pay..

In the end, we paid down the card immediately, and pushed through another 30K.. Amex is looking at the cardholders' ability to pay, and gradually increasing the limit as transactions continue, and the ability to pay down the balance on time continues..
