(Updated 2013) I have a Gold card with a bunch of points on it and want to use them for a trip. How many American Express points are needed for a roundtrip flight domestically? Does it work as a normal frequently flyer program would where there are different flat rate tiers for flights, such as 25,000 for off peak and 37,500 for peak? Does it work where the Membership Rewards points are converted to a cash value? Any and all input is appreciated because this will be the first time I have redeemed my points since getting an American Express credit card.
