FYI
The AMEX Rewards program through MBNA is the same exact thing as WorldPoints. So if you are switching to avoid WorldPoints, you'd might as well cancel.

MBNA has really gone downhill with their offerings of quasi-mileage award programs. I originally started with them as a customer with the NEA charge card, which allowed redemptions within zone ($300 max) for 10000 points, and anywhere in the 48 for 15000 ($500 max). They cancelled this program after about a year, and moved me into the prior WorldPoints program.

Over the past year or so WorldPoints has seriously changed it's T&Cs that severely limit your ability to pick which flight you want to take. They automatically book you on the cheapest available flight, even if it is with a ridiculous connection. They also lowered the cap to $400 and no longer offer an in-zone redemption level (helpful for me with frequent travel EWR-Florida and Atlanta).

Other programs (such as Chase Travel Rewards) give you up to $500 in credit for essentially any flight you want. I have switched over to this card and will soon be cancelling my MBNA after redeeming my remaining 25000 points. I would prefer to switch this over to a Merrill Lynch card, but it does not seem possible based on the posts here (I will still call and find out).

The only thing I will miss is the very competent and helpful people that work in customer service at MBNA - I have never had a problem with them and always hang up the phone satisfied.
